Description:

I rencountered two errors while installing PostgreSQL.

The errors are as follow:

1. A non-fatal error occurred whilst creating menu shortcuts.
2. Problem running post-install step. Installation may not complete
correctly for the database cluster.

I tried updating Security and Privacy settings, as well as reinstalling
PostgreSQL in a non-default folder. Neither method worked.
