I am running postgres 10.4 on CentOS 7.5. I am having trouble getting the plperl language extension going :
netdrms02.nispdc.nso.edu:5432 <http://netdrms02.nispdc.nso.edu:5432> postgres@nsocu=# CREATE EXTENSION plperl; ERROR: 58P01: could not open extension control file "/usr/pgsql-10/share/extension/plperl.control": No such file or directory LOCATION: parse_extension_control_file, extension.c:494
Sure enough that file is not there :
[production@netdrms02 ~]$ ls /usr/pgsql-10/share/extension/ plpgsql--1.0.sql plpgsql.control plpgsql--unpackaged--1.0.sql
Yet plperl would seem to be installed :
# yum list | grep postgres | grep perl postgresql-plperl.x86_64 9.2.23-3.el7_4 base postgresql10-plperl.x86_64 10.4-1PGDG.rhel7 pgdg10
So where did you get the packages to install Postgres itself?:
a) The CentOsS repos
b) The PGDG repos
I need to do this for both plperl and plperlu. I think there is perhaps something I don't have installed, but I can't tell what? I apologize if this is obvious, the language extensions are not something I deal with regularly.
If it helps, here is the result of "select version();" : PostgreSQL 10.4 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28), 64-bit
Thanks for considering this,
Niles.
