extras/fix_pikapods_dump.py patches two confirmed Adminer PostgreSQL-export
bugs that otherwise make a PikaPods Mattermost migration fail outright:
unquoted enum-label DEFAULT values (Postgres reads the bare label as a
column reference and rejects the CREATE TABLE) and boolean columns
serialized as bare 0/1 instead of true/false (Postgres doesn't implicitly
cast integers to boolean). Boolean columns are discovered by actually
parsing each CREATE TABLE in the dump rather than working from a
hand-curated list — Postgres only reports the first bad column per failed
row, so a list built from error output alone would likely be incomplete.
Already verified earlier this session against a real local Postgres 16
instance; reviewed now for anything needing redaction before committing —
it's a generic text-processing tool with no hostnames, credentials, file
paths, or personal data in it, so nothing needed changing.
Cross-referenced from the generated migrate-from-pikapods.sh's header
comment (services/mattermost.sh) so anyone hitting a CREATE TYPE/CREATE
TABLE or boolean-column import error is pointed at the fix instead of
having to rediscover it.
