Hi Frank,
Presumably pg_last_error() doesn't do anything useful until after the
database connection has been made...
That behaviour doesn't seem particularly unnatural to me, really, though
this seems an unlikely place to be posting a bug about it. If it's a
problem for you perhaps you should file a bug with the developer.
Alternatively, does pg_errormessage() have the same flaw, or does that
give you the error details that you're after? That's what I use in my
own code, although I note that in my own code I only log the fact of
connection failure, without logging the reason, and I use that for
getting the error when a query fails. Perhaps something I should
improve :-)
Cheers,
Andrew.
