annotate db/sat_pubsub_update_4_5.sql @ 428:34bd55179e22

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
environment variables can now be used to set options: if an environment variable is set using `SAT_PUBSUB_[OPTION NAME]` it will be used if not specified directly in command line. Options are retrieved in this order of priority: - command line (highest priority) - environment variable - option set in `sat.conf` For database options, following PostgreSQL aliases can also be used: PGUSER, PGDATABASE, PGPASSWORD, PGHOST, PGPORT.
