what sub-package shoudl we use for pg_rewind

Hi Devrim,

I'm tempted to put pg_rewind tool into 'postgresql-server.rpm', but
postgresql-9.5.spec in pgrms installs this into 'postgresql.rpm'.

What is better approach?

Thanks, Pavel

Awesome question. Here are the list of binaries that we install with
each RPM:

$ rpm -ql postgresql95|grep bin
/usr/pgsql-9.5/bin/clusterdb
/usr/pgsql-9.5/bin/createdb
/usr/pgsql-9.5/bin/createlang
/usr/pgsql-9.5/bin/createuser
/usr/pgsql-9.5/bin/dropdb
/usr/pgsql-9.5/bin/droplang
/usr/pgsql-9.5/bin/dropuser
/usr/pgsql-9.5/bin/pg_archivecleanup
/usr/pgsql-9.5/bin/pg_basebackup
/usr/pgsql-9.5/bin/pg_config
/usr/pgsql-9.5/bin/pg_dump
/usr/pgsql-9.5/bin/pg_dumpall
/usr/pgsql-9.5/bin/pg_isready
/usr/pgsql-9.5/bin/pg_receivexlog
/usr/pgsql-9.5/bin/pg_restore
/usr/pgsql-9.5/bin/pg_rewind
/usr/pgsql-9.5/bin/pg_test_fsync
/usr/pgsql-9.5/bin/pg_test_timing
/usr/pgsql-9.5/bin/pg_upgrade
/usr/pgsql-9.5/bin/pg_xlogdump
/usr/pgsql-9.5/bin/pgbench
/usr/pgsql-9.5/bin/psql
/usr/pgsql-9.5/bin/reindexdb
/usr/pgsql-9.5/bin/vacuumdb

$ rpm -ql postgresql95-server|grep bin
/usr/pgsql-9.5/bin/initdb
/usr/pgsql-9.5/bin/pg_controldata
/usr/pgsql-9.5/bin/pg_ctl
/usr/pgsql-9.5/bin/pg_resetxlog
/usr/pgsql-9.5/bin/postgres
/usr/pgsql-9.5/bin/postgresql95-check-db-dir
/usr/pgsql-9.5/bin/postgresql95-setup
/usr/pgsql-9.5/bin/postmaster

I pushed it into main package, because it is not a "server" tool, and
more like a utility. It is not something like pg_ctl or initdb.

Why do you want to push it into -server subpackage?

It kind of sounds like tool useful for implementing slave-to-master
promotion (but both-ways).  And, given by tool's parameters, at least one
"data directory" needs to be local.

Thus I would bet it does not make sense to have this tool installed
without server package.

Good point, so then we will need to move pg_basebackup,
pg_archivecleanup, pg_receivexlog, etc, to the server package, right?

I'd like to include only the core-server related tools in that
subpackage.

Jeff, what do you think?

Ah, I missed those are in postgresql-9.5.rpm too -- so IMO yes.   Except
that in Fedora we install pg_archivecleanup into postgresql-contrib (which
reflects that it is in ./contrib/ subdirectory in upstream source, since
the dist-git commit 4753f369).

Thanks, Pavel

Well, I'll leave RH packaging decision to you, for sure. It's been a
while since PGDG RPMs and RH packages have chosen separate ways (like
postgresql-setup stuff). and our multi version paths. I still think
what we do in PGDG RPMs are consistent at some point, but I am open to
hear ideas from other people, too.
