Here's my attempt for it.  As conditional port module seems trouble,
I set up an unconditional pgGetpeereid() that is always defined.

The result seems nice.  It also fixes broken ifdeffery where
"#error missing implementation" is unreachable, instead
pqGetpwuid() can be reached with undefined uid.

It does drop 2 error messages for HAVE_UNIX_SOCKET but no method
for getting peer id.  Now it will give plain ENOSYS in that case.
If really required, the message can be picked based on errno,
but it does not seem worth it.
