Hi, I have postgresql version 15 running on centos7.
I have below query that reads hostname from /tmp directory: psql postgres -A -t -p 5432 -h /tmp/ -c 'SELECT pg_is_in_recovery();' so below are my questions: 1. Is the psql client reading the socket file that resides in the /tmp directory to fetch the hostname ? 2. I saw the socket file in /tmp and it is empty. Then how is the psql client still reading the socket file successfully for hostname ? this is my socket looks ( the size is 0 as the file is empty): srwxrwxrwx. 1 postgres postgres 0 Apr 22 12:47 .s.PGSQL.5432 Please help me clarify these doubts. Regards.
