Hi,
I am trying to setup the debugger plugin on Centos 7 where PG 13 server has been setup using the git repository located here - https://git.postgresql.org/gitweb/?p=pldebugger.git;a=summary
The OS version is CentOS Linux release 7.9.2009 (Core).
However, after making the changes to postgresql.conf to reference the plugin_debugger.so library that was created on CentOS 7 using several variations to ensure that the .so file was being referenced -
shared_preload_libraries = '/usr/lib64/pgsql/plugin_debugger'
or
shared_preload_libraries = 'plugin_debugger'
or
shared_preload_libraries = '/usr/pgsql-13/lib/plugin_debugger.so'
I encountered the following error during postgres start up–
-- Unit postgresql-13.service has begun starting up.

Though the library wasn’t loaded, I attempted to add the extension at the DB level using
CREATE EXTENSION pldbgapi;
But got the following error –
ERROR: could not load library "/usr/pgsql-13/lib/plugin_debugger.so": /usr/pgsql-13/lib/plugin_debugger.so: undefined symbol: LWLockAssign SQL state: 58P01
Can you please help with getting the debugger working ?
Thanks
Ankit
