Crunchy Data announces the release of PGO, the Postgres Operator 4.5.5.

The PostgreSQL Operator is released in conjunction with the Crunchy Container Suite.

PostgreSQL Operator 4.5.5 release includes the following software versions upgrades:

  • PostgreSQL versions 13.5, 12.9, 11.14, 10.19 and 9.6.24 are now available.
  • The pgnodemx extension is now at version 1.0.6.
  • pgBouncer is now at version 1.16.1


  • The default pgo-backrest-repo-config Secret can now be automatically generated by the Operator. This functionality was backpatched from v4.6 to help support the fix around automatically updating the AWS CA values.


  • Ensure the pgo create pgbouncer command can set CPU and memory limits via --cpu-limit and --memory-limit respectively.
  • Update the aws-s3-ca.crt value to use the newer CAs provided by AWS. If a PostgreSQL cluster is using the old default CA, PGO will update the general one kept in the pgo-backrest-repo-config Secret and pgo upgrade will update it for a specific cluster.
  • Allow for the original primary instance to be scaled down after running pgo upgrade.
