fn register_pg_catalog_compat(ctx: &SessionContext)Expand description
Register the session-level (not function-registry) Postgres-compatibility
extension sourced from datafusion-pg-catalog: widen Postgres int4
bounds to int8 for generate_series/range (their stock implementations
require int8 literals, and DF invokes them at planning time, before any
analyzer rule can run).
The oid-alias type planner is supplied per SQL-planner context by
DfContextProviderAdapter::get_type_planner.
Forward oid-alias name->oid resolution is handled at SQL-parse time by the
PostgresCompatibilityParser’s built-in rewrite rule, not here.
