kandi X-RAY | pgweb Summary
Pgweb is a web-based database browser for PostgreSQL, written in Go and works on OSX, Linux and Windows machines. Main idea behind using Go for backend development is to utilize ability of the compiler to produce zero-dependency binaries for multiple platforms. Pgweb was created as an attempt to build very simple and portable application to work with local or remote PostgreSQL databases.

QUESTION
I have a flyway job that is meant to be performing migrations on a postgres database. The job doesn't seem to be running the command and inspection of the jobs logs only output flyway documentation.
ExpectationsI expect the log inspection to be a synopsis of the migrations occurred. I also have installed pgweb to allow for observability and after connecting to my postgres pod, it is clear no tables have been created at all.
Here is a photo of the expected output from kubectl logs flyway-pod
What I getThis is the output of kubectl logs flyway-pod As you can see it prints the usage guide rather than a sign that the migration occurred.
What I have tried -explanationI have so far been moving the connection command around.
I have commented out the locations where I have tried placing the command. I have tried it in 3 locations.
- Inside the original Flyway Dockerfile and nowhere else.
- Inside the docker compose file near the flyway service and nowhere else.
- Inside the Kubernetes Flyway job and nowhere else.
Here are my files and setup.
Kubernetes filesWhat follows are the relevant Kubernetes files used to setup my cluster.
Flyway Job:Here is the Flyway job:

QUESTION
In my project, I am asked to implement a text query service on the database we are using; Postgresql. I have used Postgresql Full Text Search features, which works fairly fine in terms of time. One problem about full text search is, it does not have fuzzy search abilities. On the other hand, there is an extension named pgtrgm providing functions and operators for determining the similarity of alphanumeric text. Also there are several examples of text search using pgtrgm like:
...ANSWER
Answered 2020-Feb-25 at 15:15The difference is quite huge - in fuzzy search, you're searching for a similar result, in full-text search - for the exact same. If one is more appropriate than the other is the matter of use-case.
If you don't need fuzziness, don't use it, it's a huge performance overhead because it has to match the text not exactly, but also try other combinations.
QUESTION
I'm interesting in applying an index for querying across multiple columns using Postgres full text search.
According to the docs, I could apply a multi-column index like so:
...ANSWER
Answered 2020-Jan-10 at 01:14Would the to_tsvector function used in the WHERE clause have to be in precisely the same format as what was used in the index?
Yes. It will ignore things like whitespace differences and extraneous parentheses. But other than that, they must be the same.
Would the following queries still make use of the index?:
No.
Note that what you have here is expression index, where the expression references multiple columns. It is not the same thing as a multi-column index.
