Thread: pgsql: Don't convert debug/notice/warning messages into errors just

Log Message:
-----------
Don't convert debug/notice/warning messages into errors just because
they occur inside error processing.  This is a back-port of a logic
change already present in 8.0.  Partial fix for bug#1976 --- doesn't
cure the wrong-encoding problem, but at least stops it from causing
unintended ERRORs.
