Use psql with -E and then issue any variety of \d style commands to find out what psql does to display indexes, functions, sequences etc. However, be aware that checking for the existence of an appropriately named table/function doesn't give any guarantuee about what they really *are*. We do something similar during database upgrade migrations: we calculate a hash over our tables with columns and column datatypes (tables only as they hold the real data). Only if the hash matches an expected value do we migrate (change) the tables themselves. Views, functions, indexes, constraints can all be re-run from scratch upon failure without affecting the data in the tables. http://cvs.savannah.gnu.org/viewvc/gnumed/gnumed/server/sql/gmSchemaRevisionViews.sql?root=gnumed&view=markup and now http://cvs.savannah.gnu.org/viewvc/gnumed/gnumed/server/sql/v5-v6/dynamic/gm-schema.sql?root=gnumed&view=markup Karsten -- GPG key ID E4071346 @ wwwkeys.pgp.net E167 67FD A291 2BEA 73BD 4537 78B9 A9F9 E407 1346 ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
