Re: perl path issue

Hi Adrian,

Yes am using edb standard edition and installed pgbackrest in prod and dev.

nothing different am trying to restore the backup prod to dev cluster .

* Can't load '/usr/lib64/perl5/vendor_perl/auto/DBD/Pg/Pg.so' for
module DBD::Pg: libpq.so.5: cannot open shared object file: No such file or
directory at /usr/lib64/perl5/DynaLoader.pm line 190.*
at /loader/0x1ec1528/pgBackRest/Db.pm line 10.
at /loader/0x1ec1528/pgBackRest/Main.pm line 12.
pgBackRest::Main::__ANON__('Can\'t load
\'/usr/lib64/perl5/vendor_perl/auto/DBD/Pg/Pg.so\...') called at
/usr/share/perl5/vendor_perl/Carp.pm line 100

May be above path is corrupt or something issue not able to load the path.

Regards,
Prakash.R
