Revision 429/430

_{June 28, 2024}

Dear community,

Canonical’s newest Charmed PostgreSQL operator has been published in the 14/stable channel

Due to the newly added support for arm64 architecture, the PostgreSQL charm now releases two revisions simultaneously:

To make sure you deploy for the right architecture, we recommend setting an architecture constraint for your entire juju model.

Otherwise, it can be done at deploy time with the --constraints flag:

juju deploy postgresql --constraints arch=<arch>

where <arch> can be amd64 or arm64.
