Thread: pgsql: Modify various power 2 calculations to use new helper functions
Modify various power 2 calculations to use new helper functions First pass of modifying various places that obtain the next power of 2 of a number and make them use the new functions added in pg_bitutils.h instead. This also removes the _hash_log2() function. There are no longer any callers in core. Other users can swap their _hash_log2(n) call to make use of pg_ceil_log2_32(n).
