Not sure if this applies with Postgres but did you also recompile the stored
procedures? If I remember correctly Sybase and Informix (?) required store
procedured to be recompiled after DDL to tables they used, and Oracle often
invalidates any functions, views, packages and procedures if they have any
relation to the modified table.
