A child table can specify a compression or storage method different from its parents. This was previously an error. (But this was inconsistently enforced because for example the settings could be changed later using ALTER TABLE.) This now also allows an explicit override if multiple parents have different compression or storage settings, which was previously an error that could not be overridden. The compression and storage properties remains unchanged in a child inheriting from parent(s) after its creation, i.e., when using ALTER TABLE ... INHERIT. (This is not changed.) Before this change, the error detail would mention the first pair of conflicting parent compression or storage methods. But with this change it waits till the child specification is considered by which time we may have encountered many such conflicting pairs. Hence the error detail after this change does not include the conflicting compression/storage methods. Those can be obtained from parent definitions if necessary. The code to maintain list of all conflicting methods or even the first conflicting pair does not seem worth the convenience it offers. This change is inline with what we do with conflicting default values. Before this commit, the specified storage method could be stored in ColumnDef::storage (CREATE TABLE ... LIKE) or ColumnDef::storage_name (CREATE TABLE ...). This caused the MergeChildAttribute() and MergeInheritedAttribute() to ignore a storage method specified in the child definition since it looked only at ColumnDef::storage. This commit removes ColumnDef::storage and instead uses ColumnDef::storage_name to save any storage method specification. This is similar to how compression method specification is handled.

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
