pgsql: Revoke pg_stat_statements_reset() permissions

Revoke pg_stat_statements_reset() permissions

Commit 25fff40 has granted execute permission of the function
pg_stat_statements_reset() to default role "pg_read_all_stats", but this
role is meant to read statistics, and not to reset them.  The
permissions on this function are revoked from "pg_read_all_stats".  The
version of pg_stat_statements is bumped up in consequence.
