Thanks Jeff,
No triggers or foreign key constrains:
psql:postgres@cipafilter = \d+ titles
Table "public.titles"
Column │ Type │ Modifiers
│ Storage │ Stats target │ Description
─────────┼───────────────────┼──────────────────────────────────────────────────────────┼──────────┼──────────────┼─────────────
title │ character varying │
│ extended │ │
titleid │ integer │ not null default
nextval('titles_titleid_seq'::regclass) │ plain │ │
Indexes:
"titles_pkey" PRIMARY KEY, btree (titleid)
"titles_md5_title_idx" btree (md5(title::text))
Do you see anything in there that would be problematic?
