# This script will run an SQL file through PostgreSQL and create an
# error report if errors are found.
#
# For some strange reason, NAV sql scripts like to drop all tables and
# sequences before they are created.  These don't exist in an empty
# database, and these DROPs are therefore errors.  This script will
# filter out lines matching the regex "^DROP", by commenting them out.
