Re: Changing postgres User

Hi Adrian,

Thank you for the link to the documentation however it is the UID and GID of 1001:1001 that is required, not the username which I believe this is intended for? Is there a similar option for UID and GID? Apologies if my original question was not clear in this manner.

Zac

Why?

Per:

You can have the initdb create the cluster as any user:

"-U username
--username=username

Sets the user name of the bootstrap superuser. This defaults to the
name of the operating-system user running initdb.
