+
+pg_amcheck is a command-line tool for running the amcheck extension.
+
+Running the regression tests
+============================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+Also, to use "make installcheck", you must have built and installed
+contrib/amcheck and contrib/pageinspect in addition to the core code.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+See src/test/perl/README for more info about running these tests.

+# This regression test demonstrates that the pg_amcheck binary correctly
+# identifies specific kinds of corruption within pages.  To test this, we need
+# a mechanism to create corrupt pages with predictable, repeatable corruption.
+# The postgres backend cannot be expected to help us with this, as its design
+# is not consistent with the goal of intentionally corrupting pages.
+#
+# Instead, we create a table to corrupt, and with careful consideration of how
+# postgresql lays out heap pages, we seek to offsets within the page and
+# overwrite deliberately chosen bytes with specific values calculated to
+# corrupt the page in expected ways.  We then verify that pg_amcheck reports
+# the corruption, and that it runs without crashing.  Note that the backend
+# cannot simply be started to run queries against the corrupt table, as the
+# backend will crash, at least for some of the corruption types we generate.
+#
+# Autovacuum potentially touching the table in the background makes the exact
+# behavior of this test harder to reason about.  We turn it off to keep things
+# simpler.  We use a "belt and suspenders" approach, turning it off for the
+# system generally in postgresql.conf, and turning it off specifically for the
+# test table.
+#
+# This test depends on the table being written to the heap file exactly as we
+# expect it to be, so we take care to arrange the columns of the table, and
+# insert rows of the table, that give predictable sizes and locations within
+# the table page.
+#
+# The HeapTupleHeaderData has 23 bytes of fixed size fields before the variable
+# length t_bits[] array.  We have exactly 3 columns in the table, so natts = 3,
+# t_bits is 1 byte long, and t_hoff = MAXALIGN(23 + 1) = 24.
+#
+# We're not too fussy about which datatypes we use for the test, but we do care
+# about some specific properties.  We'd like to test both fixed size and
+# varlena types.  We'd like some varlena data inline and some toasted.  And
+# we'd like the layout of the table such that the datums land at predictable
+# offsets within the tuple.  We choose a structure without padding on all
+# supported architectures:
+#
+# 	a BIGINT
+#	b TEXT
+#	c TEXT
+#
+# We always insert a 7-ascii character string into field 'b', which with a
+# 1-byte varlena header gives an 8 byte inline value.  We always insert a long
+# text string in field 'c', long enough to force toast storage.
+#
+# We choose to read and write binary copies of our table's tuples, using perl's
+# pack() and unpack() functions.  Perl uses a packing code system in which:
+#
+#	l = "signed 32-bit Long",
+#	L = "Unsigned 32-bit Long",
+#	S = "Unsigned 16-bit Short",
+#	C = "Unsigned 8-bit Octet",
+#
+# Each tuple in our table has a layout as follows:
+#
+#    xx xx xx xx            t_xmin: xxxx		offset = 0		L
+#    xx xx xx xx            t_xmax: xxxx		offset = 4		L
+#    xx xx xx xx          t_field3: xxxx		offset = 8		L
+#    xx xx                   bi_hi: xx			offset = 12		S
+#    xx xx                   bi_lo: xx			offset = 14		S
+#    xx xx                ip_posid: xx			offset = 16		S
+#    xx xx             t_infomask2: xx			offset = 18		S
+#    xx xx              t_infomask: xx			offset = 20		S
+#    xx                     t_hoff: x			offset = 22		C
+#    xx                     t_bits: x			offset = 23		C
+#    xx xx xx xx xx xx xx xx   'a': xxxxxxxx	offset = 24		LL
