# See http://people.planetpostgresql.org/peter/index.php?/archives/18-Readding-implicit-casts-in-PostgreSQL-8.3.html
# for the context. This is the result produced by the also included shell
# script pg83-add-old-casts.sh.
#
# Use at your own risk. Version 8.3+ of PostgreSQL has not been tested yet with
# these casts added. Adding them might make v8.3 work with bioperl-db, but it
# is not tested.
#
# Obviously, DO NOT run this in PostgreSQL prior to v8.3. It's not needed, and
# hence if anything will cause damage.
