Thread: Write to file from pgplsql function
Hello, is there a way to write to a file in the filesystem from a pgplsql function? The reason for this is the architecture of our user system: Each new database has a file in $PGDATA/users with a list ofusers who are allowed to connect to this database. In pg_hba.conf is a link to this file. As some users don't have filesystemprivileges, but are allowed to add users, they have to be able to call a function in postgres which adds that userto the file. I appreciate your help, or a tip to improve the user system. Sven Sporer

No, because plsql is a trusted language. You should use a untrusted language, for instance plperlu.

In 8.2, you might have another option. There is now a CONNECT privilege for databases. So you don't need to list all of your users individually in the pg_hba.conf file to give only some of them access to particular databases.
