Обсуждение: Error Codes?

I'm a bit confused about the current state of error codes in Pg.  The
docs and
the mailing list archives seem to indicate that this is a TODO item,
however,
at least when using Perl with DBD::Pg, when I call $db->err() or examine

$DBI::err I get a number back.  For instance, 7 if I try to insert too
many
columns into a row, and a 1 if the connection fails.  What's the scoop,
and if
error codes really do exist, is there a list of such codes?

Thanks,
Fran

Look at $db->errstr  That has the text version of the error code.

Yes, but I want to know about the codes, not the text.  If the codes exist,
they are easier to work with than the text.

I find this code useful. You can build a hash from which you can extract more
useful error messages.

perl -MPg <<'EOF'
print map { "$_ => ".$Pg::{$_}->()."\n" }
      sort grep { /^PGRES_/ }
      keys %Pg::
EOF

=== output ===
PGRES_BAD_RESPONSE => 5
PGRES_COMMAND_OK => 1
PGRES_CONNECTION_BAD => 1
PGRES_CONNECTION_OK => 0
PGRES_COPY_IN => 4
PGRES_COPY_OUT => 3
PGRES_EMPTY_QUERY => 0
PGRES_FATAL_ERROR => 7
PGRES_INV_ARCHIVE => 65536
PGRES_INV_READ => 262144
PGRES_INV_SMGRMASK => 65535
PGRES_INV_WRITE => 131072
PGRES_InvalidOid => 0
PGRES_NONFATAL_ERROR => 6
PGRES_TUPLES_OK => 2
