PostgreSQL is an open source object-relational database management system.
An error involving insecure search_path settings in the SECURITY DEFINER functions has been reported in PostgreSQL.
If allowed to call a SECURITY DEFINER function, an attacker could gain the SQL privileges of the owner of the called function.

# emerge --sync
# emerge --ask --oneshot --verbose "dev-db/postgresql"
In order to fix the SECURITY DEFINER functions, PostgreSQL users are
advised to refer to the PostgreSQL documentation:
