# Ideal path to minimise downtime is:
# - [recommended] perform `VACUUM (VERBOSE, ANALYZE);` on db
#    * to improve speed of db generally
# - [recommended] create manual snapshot
#    * to improve speed of upgrade process's automated snapshots
# - put site in maintenance mode
# - perform VACUUM; of postgres DB (this can be done before too but may place heavy load on db)
