# X_DB_POOLER_OPTIONS_REFUSED

## Means

the connection pooler refused the libpq options a pool connects with

## Typical cause

the pooler answered 08P01 unsupported startup parameter at connection startup: a stock PgBouncer does not forward statement_timeout, so with DATABASE_POOLER unset every role fails on its first statement

## Fix

`export DATABASE_POOLER=transaction && psql "<DATABASE_URL without its options parameter>" -c "alter role <user> set statement_timeout = '10s'" -c "alter role <user> set idle_in_transaction_session_timeout = '30s'"` — `session` on a session pool; then reopen the pooler's server connections. A refused option of your own in `DATABASE_URL`'s `options`: move it to `alter role` instead. Never `psql "$DATABASE_URL"`: the pooler refuses those options again before `alter role` runs. The error's own `fix:` cuts the parameter with `sed`, so paste that
