Hmm just noticed this in the docs for the related
SYSCS_UTIL.SYSCS_COMPRESS_TABLE procedure:
"The SYSCS_UTIL.SYSCS_COMPRESS_TABLE system procedure updates statistics
on all indexes as part of the index rebuilding process."
But no mention of that (either way) for
SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE
