Changeset 33260 for branches/4.2/src/wp-includes/wp-db.php

Message:

WPDB: When extracting the table name from a query, we had a 1000 character limit on the SQL string that would be searched. This was a hangover from when the code was imported from HyperDB, and isn't appropriate for Core, where a wider range of queries are likely to be run.

Merges [33259] to the 4.2 branch.

Fixes #32763
