With the original approach it happened cases where one connection
acquired the lock and other connection tried to release the same lock,
causing an unrecoverable failure which made the node to end.
* postgres: first step to implement partition management
* postgres_driver: use of times.now().toTime().toUnix() instead of Moment.now()
* postgres migrations: set new version to 2
* test_driver_postgres: use of assert instead of require and avoid using times.now()
* postgres_driver: better implementation of the reset method with partitions
* Remove createMessageTable, init, and deleteMessageTable procs
* postgres: ensure we use the version 15.4 in tests
* postgres_driver.nim: enhance debug logs partition addition
* ci.yml: ensure logs are printed without colors
* postgres_driver: starting the loop factory in an asynchronous task
* postgres_driver: log partition name and size when removing a partition
