libevent2 requirement in pgbouncer package (1.7.2-7) breaks install on Amazon Linux

Hi all,

It seems this recent change in the pgbouncer package breaks installation on
Amazon Linux:
https://git.postgresql.org/gitweb/?p=pgrpms.git;a=blobdiff;f=rpm/redhat/master/pgbouncer/master/pgbouncer.spec;h=a43aa7912ca4ba99df961c4de51c71be8025a5d0;hp=e86c0c7ae26d6b5808ad6bc0e1a8c0facac52b83;hb=ea84a30659ba40e8eecb57bf43b804802f106ee4;hpb=f79f757b60b26e53a5fcbe8edd170da32125e5d5

The installation fails with:

Error: Package: pgbouncer-1.7.2-7.rhel6.x86_64 (pgdg95)
Requires: libevent2 >= 2.0

Note that "libevent" seems to be the correct package for Amazon Linux:

libevent.i686 2.0.21-4.19.amzn1 amzn-main

Amazon Linux is odd in that its initially RHEL 6 based, but nowadays has
slightly different packages.

Previously the pgbouncer package worked fine, so this seems like an
unfortunate regression due to the explicit requirement in the package
definition. Maybe this can be special cased in some way?

Thanks,
Lukas
