Not really sure what caused this but most likely exiting the terminal while my rails server which was connected to PostgreSQL database was closed (not a good practice I know but lesson learned!)
I've already tried the following:
- Rebooting my machine (using MBA M1 2020)
- Restarting PostgreSQL using homebrew
brew services restart postgresql
- Re-installing PostgreSQL using Homebrew
- Updating PostgreSQL using Homebrew
- I also tried following this link but when I run
cd Library/Application\ Support/Postgresterminal tells me Postgres folder doesn't exist, so I'm kind of lost already. Although I have a feeling that deleting postmaster.pid would really fix my issue. Any help would be appreciated!

My original answer only included the troubleshooting steps below, and a workaround. I now decided to properly fix it via brute force by removing all clusters and reinstalling, since I didn't have any data there to keep. It was something along these lines, on my Ubuntu 21.04 system:

I am following this tutorial on migrating data from an oracle database to a Cloud SQL PostreSQL instance.
I am using the Google Provided Streaming Template Datastream to PostgreSQL
At a high level this is what is expected:
- Datastream exports in Avro format backfill and changed data into the specified Cloud Bucket location from the source Oracle database
- This triggers the Dataflow job to pickup the Avro files from this cloud storage location and insert into PostgreSQL instance.
When the Avro files are uploaded into the Cloud Storage location, the job is indeed triggered but when I check the target PostgreSQL database the required data has not been populated.
When I check the job logs and worker logs, there are no error logs. When the job is triggered these are the logs that logged:...

This answer is accurate as of 19th January 2022.
Upon manual debug of this dataflow, I found that the issue is due to the dataflow job is looking for a schema with the exact same name as the value passed for the parameter
databaseName and there was no other input parameter for the job using which we could pass a schema name. Therefore for this job to work, the tables will have to be created/imported into a schema with the same name as the database.
However, as @Iñigo González said this dataflow is currently in Beta and seems to have some bugs as I ran into another issue as soon as this was resolved which required me having to change the source code of the dataflow template job itself and build a custom docker image for it.
Why does this simple query result in a "division by zero" Error?...
ANSWERAnswered 2022-Jan-26 at 14:26
See the documentation:
CASEcannot prevent evaluation of an aggregate expression contained within it, because aggregate expressions are computed before other expressions in a
HAVINGclause are considered. For example, the following query can cause a division-by-zero error despite seemingly having protected against it:

The issue is that when connecting in a
docker-compose network, you have to connect to the hostname of the container, in this case
You could also use the other container's
IP but would take additional amount of work, it's simpler to just use the hostname.
In other words, you have the wrong connection string, I got this as well when connecting to
I want to query the Covalent database to find out the amount of gas paid out in the latest 100 rUSDT token transfer transactions on the RSK blockchain.
In the following SQL query I am trying to join these two tables to find out the gas fees paid for each of the latest 100 transactions....
ANSWERAnswered 2021-Dec-01 at 02:23
You need to put a date range on the query or else it will run for a very long time.
There are a huge number of rUSDT
Transfer event logs on RSK.
Scanning the full table to find all of them,
and joining these all in one go is the root cause that this query takes too long.
To solve this, for each of the tables being joined,
add a condition to the time-related fields
to limit it to a certain interval, say a month:

The node server appears to be running without issues reporting 4006 port is open. However I believe my apache config is not. The request will hang for a very very long time.

If you use a docker for your node server, then it might be set up incorrectly

If you're running two virtual servers with different IPs on the same machine, you'd want to specify the IP address in the listen directive:
