An alternative is to simply select nextval() from a separately-created
sequence object to get the serial value, then insert with that value. No
need to have a serial column then, but you do need to explicitly create the
sequence object, as opposed to SERIAL.
But I didn't understand why you care to get rid of the explicit reference to
the sequence object in your code in the first place. In PostgreSQL, at
least for the past 5 years if not longer, if you create a SERIAL column for
(schemaname, tablename, columnname), then your sequence will *always* be
"schemaname.tablename_columnname_seq". If that naming convention changes,
there will be a whole lotta breakage world-wide.
