Revert "Add TAP test to automate the equivalent of check_guc"
This reverts commit b0a55f4, to remove for now the TAP test that did the
equivalent of check_guc. The test has been using pg_config --sharedir
to find the location of postgresql.conf.sample. While the buildfarm and
normal build enviro
Consolidate VACUUM xid cutoff logic.
Push the logic for determining whether or not a VACUUM operation will be
aggressive down into vacuum_set_xid_limits(). This makes the function's
signature significantly simpler, and seems clearer overall.

Add VACUUM instrumentation for scanned pages, relfrozenxid.
Report on scanned pages within VACUUM VERBOSE and autovacuum logging.
These are pages that were physically examined during the VACUUM
operation. Note that this can include a small number of pages that were
marked all-visible in the visib
Add decoding of sequences to test_decoding
Commit 0da92dc530 improved the logical decoding infrastructure to handle
sequences, and did various changes to related parts (WAL logging etc.).
But it did not include any implementation of the new callbacks added to
OutputPluginCallbacks.
This extends t
Simplify lazy_scan_heap's handling of scanned pages.
Redefine a scanned page as any heap page that actually gets pinned by
VACUUM's first pass over the heap, regardless of whether or not the page
was cleanup locked. Although it's fundamentally impossible to prune a
heap page without a cleanup loc
Fix DROP {DATABASE,TABLESPACE} on Windows.
Previously, it was possible for DROP DATABASE, DROP TABLESPACE and ALTER
DATABASE SET TABLESPACE to fail because other backends still had file
handles open for dropped tables. Windows won't allow a directory
containing unlinked-but-still-open files to be
Don't use_physical_tlist for an IOS with non-returnable columns.

Replace Test::More plans with done_testing
Rather than doing manual book keeping to plan the number of tests to run
in each TAP suite, conclude each run with done_testing() summing up the
the number of tests that ran. This removes the need for maintaning and
updating the plan count at the expense
pg_basebackup: Allow client-side LZ4 (de)compression.
LZ4 compression can now be performed on the client using
pg_basebackup -Ft --compress client-lz4, and LZ4 decompression of
a backup compressed on the server can be performed on the client
using pg_basebackup -Fp --compress server-lz4.

Add suport for server-side LZ4 base backup compression.
LZ4 compression can be a lot faster than gzip compression, so users
may prefer it even if the compression ratio is not as good. We will
want pg_basebackup to support LZ4 compression and decompression on the
client side as well, and there is a
