Yes, with a few caveats. One recommendation is to also increase autovacuum_freeze_max_age to 500000000 (500m), which will hopefully prevent autovacuum from 'butting in' and causing issues during the process. Also, a database-wide 'VACUUM FREEZE;' should be lower-risk, if you can afford it (it will cause a lot of i/o on the system). The per-table 'VACUUM FREEZE <table>;' that the script does can end up removing clog files prematurely. > Anyone have any suggestions or changes before I commit myself to this > course of action? If you run into problems, and perhaps even before starting, you may want to pop in to #postgresql on irc.freenode.net, there are people there who can help you with this process who are very familiar with PG. Thanks, Stephen
