Hi Hackers,
I noticed several additional paths in contrib modules, beyond [1],
that are potentially suitable for streamification:
1) pgstattuple — pgstatapprox.c and parts of pgstattuple_approx_internal
2) Bloom — scan paths in blgetbitmap() and maintenance paths in blbulkdelete()
The following patches streamify those code paths. No benchmarks have
been run yet.

Feedbacks welcome.
