Subject: pgsql: Separate TBM[Shared|Private]Iterator and TBMIterateResult
Date: Sat, 15 Mar 2025 14:12:03 +0000
Message-ID: <[email protected]> (raw)
Separate TBM[Shared|Private]Iterator and TBMIterateResult
Remove the TBMIterateResult member from the TBMPrivateIterator and
TBMSharedIterator and make tbm_[shared|private_]iterate() take a
TBMIterateResult as a parameter.
This allows tidbitmap API users to manage multiple TBMIterateResults per
scan. This is required for bitmap heap scan to use the read stream API,
with which there may be multiple I/Os in flight at once, each one with a
TBMIterateResult.
