Issue when I try to compile pg_rman from source code

[TeodorChakalov]

Hello,
When I try to compile pg_rman I did the following steps:

1. make
2. make install

Everything finished successfully but create only pg_rman utility in bin folder (NOT create pg_rman.so in lib folder)

I add pg_stat_statements = 'pg_rman' in postgresql.conf, but when I try to start the server receive this error:
[remote]=:[APP]=:[user]=[db]=:58P01:651c243b.19201a::3:0FATAL: 58P01: could not access file "pg_rman": No such file or directory

OpenSSL version:
OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)

OS version:
NAME="Rocky Linux"
VERSION="9.2 (Blue Onyx)"

Postgresql version:
v14.4

Yes, you don't need to add 'pg_rman' in postgresql.conf because it's just client program.
You can see examples here.

Done. Now I receive one new error:
[pdbbo_adm@rocky-9 backup]$ pg_rman backup --backup-mode=full --with-serverlog --progress
INFO: copying database files
ERROR: query failed: ERROR: function pg_backup_start(unknown, unknown) does not exist
LINE 1: SELECT * from pg_walfile_name_offset(pg_backup_start($1, $2)...
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
query was: SELECT * from pg_walfile_name_offset(pg_backup_start($1, $2))

Could you please suggest what exactly is the problem ?

I think the reason is that function name of PostgreSQL was changed.
You need to compile with the branch REL_14_STABLE corresponding your PostgreSQL version.

By the way, it's easier to use the rpm package(pg_rman-1.3.15-1.pg14.rhel9.x86_64.rpm).
