Subject: pgAdmin4 v9.10 error -- connection failed: FATAL: database "24136" does not exist
Date: Sat, 29 Nov 2025 10:44:45 -0600
Message-ID: <CAKAfO9TS4zQwq8KpyYvxgo6S6Ci_-5axdPEzhMZoSDOOUik-hg@mail.gmail.com> (raw)

This is my first pgAdmin4 post.

On my cloud server (x.x.x.x), I have been running postgres v14 for months
with no problem.

And I have been connecting to cloud postgres via pgAdmin4 (through v9.9) on
my MacBook Air (Mac OS v15.6.1, chip Apple M2) for months with no problem,
successfully using Object Explorer, Query tool, and PSQL tool.

And I have been connecting to cloud postgres via Homebrew-installed psql on
my local Mac with no problem.

I recently changed my postgres environment:

   - updated to pgAdmin4 v9.10
   - added a postgres v17 server instance on the same IP address as my
   cloud server, using a different port
   - installed postgres v17 on my laptop so that I would have updated psql
   client


Following these changes, at least briefly, I maintained full functionality
of both postgres v14 and v17 instances, full connectivity via pgAdmin4
v9.10, and full connectivity via psql on my laptop.

Then, inexplicably, for the past few days, I have lost connectivity to
postgres v14 and v17 , ONLY via pgAdmin4 v9.10 Query Tool and PSQL Tool.
Connection attempt in Query Tool, for example, throws this error:

connection failed: connection to server at "xx.xx.xx.xx", port 5xxx failed:
FATAL: database "24136" does not exist

(Note:  "x" in the text above is redacted data)

"24136" is a mystery number. I do not have a database named "24136".  And
"24136" does not appear in any field in my connection parameters in Query
Tool.

I still have connectivity to postgres v14 and v17 via Object Explorer in
pgAdmin4 v9.10.

And I still have full connectivity to postgres v14 and v17 via laptop psql.

Any help appreciated.
