PostgreSQL (pg_hba.conf / postgresql.conf) The connection to the server was lost. Attempting reset: Failed

0

I have a problem with Postgres that others seem to have found but the solutions that are given somehow do not work for me. I explain:

WHAT I USE

  • MacOS 10.15.6
  • Installed through Homebrew
  • PostgreSQL 12.2 on x86_64-apple-darwin, compiled by Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn), 64-bit

THE TRIGGER EVENT

I have been doing queries without problems but some of them crash my system, here is one of the examples

SELECT w2.id AS "id"
FROM weather w1
JOIN weather w2
    ON EXTRACT(DAY FROM CAST(w2.recorddate AS TIMESTAMP)-CAST(w1.recorddate AS TIMESTAMP)) = 1
        AND w2.temperature > w1.temperature;

THE ERROR

server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

I tried on PgAdmin and it also crashes.

THINGS I HAVE CHECKED

The pg_hba.conf file

  • I tried some of the suggestions in this thread without success

The postgresql.conf file

  • I tried adding listen_addresses = '*' to the end of the file without success

CURRENT SETTINGS

I went back to the defaults I had originally but now I am not sure if everything is in order

My pg_hba.conf file looks like this:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

My postgresql.conf has the following settings

  • listen_addresses = 'localhost'
  • port = 5432

QUESTION

Any suggestion on where to look, what to reinstall, or what to do? It is a bit uncomfortable not being able to run certain queries.

Thanks!

This looks like a known issue where JIT code is not signed properly and triggers security errors on MacOS. I thought a fix for this was already released, so I don't know why you would still be seeing it on 12.4, but in any event turning jit=off should fix the problem.
