Add support for --jobs in reindexdb When doing a schema-level or a database-level operation, a list of relations to build is created which gets processed in parallel using multiple connections, based on the recent refactoring for parallel slots in src/bin/scripts/. System catalogs are processed first in a serialized fashion to prevent deadlocks, followed by the rest done in parallel.
This new option is not compatible with --system as reindexing system catalogs in parallel can lead to deadlocks, and with --index as there is no conflict handling for indexes rebuilt in parallel depending in the same relation.
