Обсуждение: [ADMIN] cfg pg_stat_statements in PG 9.5 error

Hi List ,
I am seeing the following issue:
I have to cfg  pg_stat_statements in  Pg version 9.5.1: I  create the
extension inside db , next cfg:

local_preload_libraries =
'/usr/pgsql-9.5/share/extension/pg_stat_statements'

when re-starting the PG server seeing this in errorlog :
FATAL:  access to library
"/usr/pgsql-9.5/share/extension/pg_stat_statements" is not allowed

I have root with full permission to the "/usr/pgsql-9.5/ and user
postgres with exec only , what I am missing form this cfg?

Libraries to be loaded via local_preload_libraries must be in the plugins
subdirectory.  See the manual's description of that parameter.

Tom,
I am checking my  cfg ,  I do not see a "plugins" subdirectory with
pgsql95 contrib,at least I can not find one on my host , is there other
pg conf parameter to change  so can still point to initial location: ( I
read most of the plugins must cfg as extensions now)

/usr/pgsql-9.5/share/extension


Thank you
Isabella

There isn't one in a default configuration.  It's on the head of the
local DBA to decide which libraries he/she is willing to allow in
local_preload_libraries, and copy or move them into a plugins
subdirectory.

            regards, tom lane

I solved my issue by cfg : shared_preload_libraries param.
  Tom, please what is the  general recommendation for Pg contrib module
ownership :  user postgres or root?

Thanks
Isabella

For files, Debian and PGDG gives the ownership to root.
For objects, it depends on which user launches the create extension
