From sogo backup
<0x0x555c0991b500[SQLSource]> could not run SQL 'SELECT * FROM users WHERE (c_uid = 'myname') OR (mail = 'myname')': <PostgreSQL72Exception: 0x555c09a012d0> NAME:PostgreSQL72FatalError REASON:fatal pgsql error (channel=<0x0x555c099bdb00[PostgreSQL72Channel]: connection=<0x0x555c097d3d00[PGConnection]:  connection=0x0x555c09a204f0>>): ERROR:  could not establish connection

I have many similar logs in other areas. All show a broken connection but I can easily connect with the same credentials listed in tips file using pgadmin. I have looked through the places listed in the forums for similar errors but they are for different versions or problems. I cannot trace where the issue originates. The proper credentials are listed everywhere I look. All the sogo.conf strings seem to use the sogo user but the errors are for vmail user(?). All of my sogo access is down but this should give an idea of where the fracture is.

All kinds in Sogo log:
