kandi X-RAY | pg_snakeoil Summary
Running typical on-access antivirus software on a PostgreSQL server has severe drawbacks such as severely affecting performance or making the filesystem unreliable. The failure modes are extremely problematic when a non-PostgreSQL-aware scanner blocks access to a file due to viruses, or even false-positives and bugs in the scanner software. We typically recommend not to run such software on PostgreSQL servers, as PostgreSQL knows how to discern between code and data and will not execute any viruses stored in a database. However, running anti-virus software is sometimes required by local policy. pg_snakeoil provides ClamAV scanning of all data in PostgreSQL in a way that does not interfere with the proper functioning of PostgreSQL and does not cause collateral damage or unnecessary downtimes.

I want to be able to (at run time) create or alter a DB schema dynamically on a particular event (e.g. click of a button) using FormHandler microservice of Gramex.

QUESTION
I am getting the following error while trying to upload a dataset to Hub (dataset format for AI) S3SetError: Connection was closed before we received a valid response from endpoint URL: "<...>".
So, I tried to delete the dataset and it is throwing this error below.
CorruptedMetaError: 'boxes/tensor_meta.json' and 'boxes/chunks_index/unsharded' have a record of different numbers of samples. Got 0 and 6103 respectively.
Using Hub version: v2.3.1
...ANSWER
Answered 2022-Mar-24 at 01:06Seems like when you were uploading the dataset the runtime got interrupted which led to the corruption of the data you were trying to upload. Using force=True while deleting should allow you to delete it.
For more information feel free to check out the Hub API basics docs for details on how to delete datasets in Hub.
If you stop uploading a Hub dataset midway through your dataset will be only partially uploaded to Hub. So, you will need to restart the upload. If you would like to re-create the dataset, you can use the overwrite = True flag in hub.empty(overwrite = True). If you are making updates to an existing dataset, you should use version control to checkpoint the states that are in good shape.
QUESTION
I ran into an issue that I haven't found a solution to yet. I have a collection with dozens of documents that every one of the documents contains a list (let's use the name 'list' as a key for that list) with ids of other documents(they are connected in some way).
some of the documents in the collection were deleted and I try to find all the documents that contain the ids of documents that do not exist anymore in the collection.
example:
As to the example above: I want to get the document with the id : 5e3266e9bd724a000107a902 because it contains a list with the id 5e32a7f7bd724a00012c1104 that does not exist anymore.

Answered 2022-Mar-02 at 03:10Here is a solution that works exploiting $lookup on the same collection (think "self-JOIN"):
QUESTION
Given a connection to the PostgreSQL database for user 'Alice', is there a statement that could be executed to switch to user 'Bob'?
Motivation: Looking to avoid having separate pools for each user (i.e. re-use a connection that was previously used by another user).
...ANSWER
Answered 2022-Mar-01 at 22:09In PgAdmin open part Login/Group roles. Right click and in opened window enter new user, set permission and defined password. After refresh you will see e.g. Alice in Login/Group roles. After that open database with logged user. Click on something like mondial/postgres@PostgresSQL (db/user@server) and choose new connection. Chose which db wish to use and user wich will be connected on db.
After that you will have mondial/Alice@PostgresSQL
QUESTION
ANSWER
Answered 2022-Feb-28 at 12:43The problem consist from creating connection in separate file (must be create in App).
QUESTION
As the title suggests I'm wondering how to create an effective index for GROUP BY queries in CosmosDB.
Say the documents look something like:
...ANSWER
Answered 2021-Sep-27 at 20:51Currently GROUP BY does not not yet use the index.
This is currently being worked on. I would revisit sometime towards the end of the year to verify it is supported.

i have a database field that is set to decimal, while in my Go project i am having problem choosing which datatype can be use. each time i send a create reuquest to my code, i get a "cannot marshal 'decimal' into #golang datatype#
this my database schema
...ANSWER
Answered 2022-Feb-15 at 12:13If you look into documentation for Gocql package, then you will see that the decimal is mapped to the Go's infDec data type (see its doc) so you need to use it instead of Float64.

- Hi, we are trying to upgrade 2.0.202 from 1.4.200. We are getting an error related to running our tests. While persisting data we are getting below error. Any suggestions?
Caused by: org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: NULL not allowed for column "***"; SQL statement:
...ANSWER
Answered 2022-Jan-31 at 01:05You cannot use H2 2.0.202 with Hibernate ORM 5.6, because H2Dialect in Hibernate ORM produces invalid SQL for H2, H2 2.x is more restrictive and doesn't accept it by default.
H2 2.0.204 and later versions (current version is 2.1.210) have a LEGACY compatibility mode, it can be enabled by appending ;MODE=LEGACY to JDBC URL. This mode provides some limited compatibility with old versions of H2.
This trick shouldn't be required for Hibernate ORM 6.0 when it will be released.
Edited
Changes for H2 2.x.y were backported to Hibernate ORM 5.6.5.
QUESTION
I am confused in choosing database service for my flutter application. I started using firebase but as it is based on NoSQL , But if i am getting the need for rows and columns for my data which backend service should i use!.
...ANSWER
Answered 2022-Jan-23 at 23:20I think it depends on how you want to access the data. If you're wanting to stream and push notifications, I would stick with Firebase. If you just need to get and post data, focus more on api implementation. With a solid rest api, you can change up your database/backend all you want and just have to update the api, not your app.
I, personally, suggest searching around for data modeling techniques in Firebase. Check out the Fireship channel on youtube. In his channel's videos, search for modeling and you'll find a ton of info on Firebase data modeling. Many will reference Angular, but the techniques are the same.
