Database Error Code· An error code returned by a database server such as PostgreSQL or MySQL.

What it means

program_limit_exceeded — a hard internal limit was hit.

How to fix it

  1. Simplify the query to reduce expression depth or column count.
  2. Increase any configurable limits such as max_locks_per_transaction in postgresql.conf.
  3. Refactor to break a very wide select list or deeply nested subquery into separate queries.
