Comment:

 In [changeset:"42549"]:
 {{{
 #!CommitTicketReference repository="" revision="42549"
 WPDB: Use a PCRE syntax which supports PCRE compiled between 2003 and
 2006.

 This fixes a PHP Warning in `wpdb::parse_db_host()` when WordPress is used
 with (sometimes a modern) PHP that's compiled against an ancient PCRE
 version.

 Fixes #43109 for trunk.
