Changeset 45707 for trunk/src/wp-includes/wp-db.php

Message:

Database: Use a strict comparison for has_filter() check in wpdb::placeholder_escape().

The filter is added with a priority of 0, so a loose comparison had an unintended effect of adding the filter on every call.

Props withinboredom.
Fixes #47430.
