#5019: Add support for pcre2
----------------------------+---------------------------
 Reporter:  Bas Couwenberg  |      Owner:  pramsey
     Type:  enhancement     |     Status:  new
 Priority:  medium          |  Milestone:  PostGIS 3.2.0
Component:  postgis         |    Version:  master
 Keywords:                  |
----------------------------+---------------------------
 PostGIS currently requires the deprecated [https://pcre.org/ PCRE library]
 (`pcre.h`), as used by the Debian package via libpcre3-dev.

 The maintainer of the pcre3 package in Debian intends to remove it in
 favour of pcre2 (`pcre2.h`), because upstream is increasingly unwilling to
 fix issues in the old PCRE library, see: https://lists.debian.org/debian-
 devel/2021/11/msg00176.html

 PostGIS currently only supports the PCRE API, it should also support the
 PCRE2 API in the address_standardizer extension.
