the strings seen during the bootstrap run. There might have been some actual point to doing that, many years ago, but as far as I can see the only value now is to conserve a bit of memory. Even if we cared about wasting a megabyte or so during the initdb run, it'd be far more effective to arrange to release memory at the end of each BKI command, instead of intentionally hanging onto strings that might never be used again. Not maintaining the table probably makes it faster too; but the main point of this patch is to get rid of a couple hundred lines of unnecessary and rather crufty code.
