pgsql: Remove a couple of strerror() calls

Remove a couple of strerror() calls

Change to using %m in the error message string. We need to be a bit
careful here to preserve errno until we need to print it.

This change avoids the use of not-thread-safe strerror() and unifies
some error message strings, and maybe makes the code appear more
consistent.
