*reads patch more carefully*

Here are my verdicts:

advanced.sgml: good
array.sgml: good
backup.sgml: unsure
catalogs.sgml: bad
client-auth.sgml: bad
config.sgml: bad
func.sgml: bad
high-availability.sgml: bad
libpq.sgml: bad
runtime.sgml: bad
spi.sgml: unsure
tsearch2.sgml: good

So I guess I'm back agreeing with you. Basically, it seems like we
ought to use <literal> if it's being used as a value that the user
might want to supply (e.g. "if you set this parameter to 0, then no
statements will be logged). It shouldn't use <literal> if it's just
being used as a number (e.g. "this query will return all airplanes
with a height of less than 30,000 feet"). The cases I'm unsure about
are the ones where we're talking about a return value (e.g. in the
event of an error, this function will return -1).
