Обсуждение: Does "vacuum analyze" contain "vacuum"?
Hi all, the docs are not clear for me. If I want (in version 7.1.x, 7.2.x) to help the analyzer AND free unused space do I have to do a vacuum vacuum analyze or is a vacuum analyze enough? I am not sure if "vacuum analyze" contains a "vacuum". Regards Holger -- PGP/GPG Key-ID: http://blackhole.pca.dfn.de:11371/pks/lookup?op=get&search=0xB5A1AFE1

I'm still using it in production (although it is getting a bit long in the tooth nowadays) Looking at the docs for 7.1, it didn't.

Well, unless the running system has known bugs. Which 7.1 and 7.2
both assuredly do.
