I always assumed it stood for "abstract data type". Most of the files in this directory seem to correspond to an SQL-level data type like intX, varchar, tsquery, ..., and contain the I/O functions for that type, plus some supporting operations and functions. Over time, it seems that this directory was also used for SQL-level functions not directly related to a single type, like windowfuncs.c and pgstatfuncs.c. The fact that ri_triggers.c lives there also might be a relict from times where you'd create FK constraint with CREATE CONSTRAINT TRIGGER and specified one of the functions from ri_triggers.c as the procedure to execute. best regards, Florian Pflug -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
