initdb currently does
PG_CMD_PUTS("ANALYZE;\nVACUUM FULL;\nVACUUM FREEZE;\n");
FREEZE is now part of FULL, so this seems redundant. Also, ANALYZE can
be run as part of VACUUM. So this could be
PG_CMD_PUTS("VACUUM FULL ANALYZE;\n");
There has been some concerns about time spent in initdb in test suites,
which is why I looked into this. In testing, this change can shave off
between 10% and 20% of the run time of initdb, so it would be kind of
useful.
The last change to this was

Clean up initdb's error handling so that it prints something more useful than just \'failed\' when there's a
problem. Per gripe from Chris Albertson.
In an unrelated change, use VACUUM FULL; VACUUM FREEZE; rather than a single VACUUM FULL FREEZE command, to
respondto my worries of a couple days ago about the reliability of doing this in one go.
That was a long time ago. Is that still applicable?
