Execute privileges
If authentication and SQL authorization are both enabled, only the
database owner has
execute privileges on this procedure by default. See "Configuring user
authentication" and "Configuring user authorization" in the
for more information.
The database owner can grant access to other users. Since this procedure can
be used to install arbitrary code (possibly from across the network) that runs
in the same Java Virtual Machine as the
database engine, the
execute privilege should be granted only to trusted users.
