Still fishy. Looks like you must have used 'agencyid'? (no
underscore)

Could be. Might also come from not naming the insert columns, which
breaks miserably if you add new columns with default values in the
future...
insert into agency values ('MyAgency2', 'MyAddr2')"
vs.
insert into agency (agency_name, street_addr) values ('MyAgency2',
'MyAddr2')"

% man psql
