Finally got to this; sorry for the delay.

Two things I noticed:

1. Did I neglect to include the documentation patch? I've attached it
here. It's necessary because of the addition of the new functions.

2. Many thanks for switching to using the network_show function
instead of the SQL-based casting I had. Can you tell me how to go
about finding such functions? Because for my 8.3 version of citext, I
have a whole bunch of functions that do casting like this:

CREATE OR REPLACE FUNCTION int8(citext)
RETURNS int8
AS 'SELECT int8( $1::text )'
LANGUAGE SQL IMMUTABLE STRICT;

CREATE OR REPLACE FUNCTION citext(int8)
RETURNS citext
AS 'SELECT text( $1 )::citext'
LANGUAGE SQL IMMUTABLE STRICT;

CREATE OR REPLACE FUNCTION int4(citext)
RETURNS int4
AS 'SELECT int4( $1::text )'
LANGUAGE SQL IMMUTABLE STRICT;

CREATE OR REPLACE FUNCTION citext(int4)
RETURNS citext
AS 'SELECT text( $1 )::citext'
LANGUAGE SQL IMMUTABLE STRICT;

...and so on. I'd love to be able to replace these (and many others)
with internal C functions, if only I could figure out what those
functions were. A pointer to making that determination (if they even
exist in 8.3) would be greatly appreciated.

Thanks,

David
