Q&A PostgreSQL multiline with HINT log

[FinecoFinit]

Question

I have issue sticking HINT to previous message, same goes to CONTEXT:

Here is log with \t \n:

< 2025-11-26 04:14:16.350 UTC - @ - 229/0 - 0 >ERROR:  could not create replication slot "***": ERROR:  all replication slots are in use$
^IHINT:  Free one or increase "max_replication_slots".$

And what I get:

{"app":"***","component":"postgresql","file":"***","host":"***","level":"error","loki_job":"***","message":"< 2025-11-26 09:24:50.086 UTC - @ - 229/0 - 0 >ERROR:  could not create replication slot \"***\": ERROR:  all replication slots are in use","origin":"databases","source_type":"file","time_slice":"2025-11-26_08","timestamp":"2025-11-26T09:24:50.180822272Z"}
{"app":"***","component":"postgresql","file":"***","host":"***","loki_job":"***","message":"\tHINT:  Free one or increase \"max_replication_slots\".","origin":"databases","source_type":"file","time_slice":"2025-11-26_08","timestamp":"2025-11-26T09:24:50.180855395Z"}

Fixed with:

multiline:
      start_pattern: '^< \d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d{3} UTC'
      mode: halt_before
      condition_pattern: '^< \d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d{3} UTC'
      timeout_ms: 3000
