While heapam reproduces the insertion order of rows well, updates can move rows to varying places depending on autovacuum activity. In most regression tests we've guarded against getting variable results due to that, but float4.sql and float8.sql had escaped notice so far because they update tables that are too small for autovacuum to pay attention to. With increasing interest in non-heap table AMs, it seems worth allowing for update behaviors that are not like heapam's. Hence, add ORDER BY to stabilize the results in case the updates put the rows in a different order. (We'll continue to assume that a seqscan will reproduce original insertion order, though. Removing that assumption would require vastly-more-invasive test changes.)

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
