Subject: pgsql: Use streaming read I/O in BRIN vacuum scan.

Message-ID: <E1vL6h1-0003EX-16@gemulon.postgresql.org> (raw)

Use streaming read I/O in BRIN vacuum scan.

This commit implements streaming read I/O for BRIN vacuum
scans. Although BRIN indexes tend to be relatively small by design,
performance tests have shown performance improvements.
