automate the building of images for each minor version of PostgreSQL and glibс

I suggest building and storing a version of images for each minor version of Postgres.

Example:

• postgresai/extended-postgres:14.4
• postgresai/extended-postgres:14.5
• postgresai/extended-postgres:14.6

The PostgreSQL project aims to make at least one minor release every quarter, on a predefined schedule. If it becomes necessary due to an important bugfix or security issue, more releases will be made between these dates, so this list should be considered a minimum. At each of these dates, a new minor release will be made for each supported version.

The target date for these releases are, unless otherwise stated, the second Thursday of February, May, August, and November. The current schedule for upcoming releases is:

• August 11th, 2022
• November 10th, 2022
• February 9th, 2023
• May 11th, 2023
