Are you sure the default was now() and not 'now'? If you still
have the 7.3.2 server running then check the table definitions.
Aside from using psql's \d commands, you could do this:
SELECT adrelid::regclass, adnum, adsrc
FROM pg_attrdef
ORDER BY adrelid, adnum;
The 7.3 documentation warns against using 'now', and the 7.4 Release
Notes mention a behavior change with respect to column defaults.
