Subject: RHEL8+9 libpcre2 dependencies in postgis packages

Hi,

on last update we got some errors updating postgis in RHEL8:

Problem 1: cannot install the best update candidate for package postgis31_13-3.1.12-10PGDG.rhel8.x86_64
- nothing provides libpcre2-8-0 needed by postgis31_13-3.1.12-13PGDG.rhel8.x86_64 from PostgreSQL_PostgreSQL13_-_RHEL_8_x86_64
Problem 2: cannot install the best update candidate for package postgis31_14-3.1.12-10PGDG.rhel8.x86_64
- nothing provides libpcre2-8-0 needed by postgis31_14-3.1.12-13PGDG.rhel8.x86_64 from PostgreSQL_PostgreSQL14_-_RHEL_8_x86_64

I've found that the dependencies changed from pcre to libpcre2-8-0:

$ rpm -qp /tmp/postgis31_13-3.1.12-13PGDG.rhel8.x86_64.rpm --requires | grep pcre
libpcre.so.1()(64bit)
libpcre2-8-0
$ rpm -qp /tmp/postgis31_13-3.1.12-10PGDG.rhel8.x86_64.rpm --requires | grep pcre
libpcre.so.1()(64bit)
pcre

The libraries libpcre2 are provided by pcre2 on RHEL8+9:

$ rpm -qf /usr/lib64/libpcre2-8.so.0
pcre2-10.32-3.el8_6.x86_64
$ rpm -qf /usr/lib64/libpcre.so.1
pcre-8.42-6.el8.x86_64

I've found the commit for postgis 3.1: https://git.postgresql.org/gitweb/?p=pgrpms.git;a=commitdiff;h=a2e39ff2a23b5c925ff0fb08340c6a7f85313...
As I can see you use pcre2 only from RHEL10 upwards, but RHEL8 and RHEL9 also provides the library with package pcre2 .

Thanks and Regards,

Christopher Lorenz
