The extension now works with PostgreSQL 10, while
retaining compatibility with version 9.6.
PostgreSQL 10 has numerous internal changes to functions and
APIs, which necessitates various glue code and compatibility
wrappers to seamlessly retain backwards compatiblity with older
versions.
Test output might also differ between versions. In particular,
the psql client generates version-specific output with `\d` and
EXPLAINs might differ due to new query optimizations. The test
suite has been modified as follows to handle these issues. First,
tests now use version-independent functions to query system
catalogs instead of using `\d`. Second, changes have been made to
the test suite to be able to verify some test outputs against
version-dependent reference files.
A recent change blocked changing types of space-partitioned hypertable
columns. However, this blocking should not apply to regular tables,
which otherwise causes a crash. This change fixes this issue by
properly checking that the the table is a hypertable.
This commit moves a lot of test setup logic to runner.sh. Also
passes the right commands to the regression infrastructure to create
appropriate users and run tests as a regular user.
When issuing rename or reindex commands that do not involve
relations, the relation rangevar in the utility statement
will be NULL.
This change adds extra checks to avoid calling, e.g.,
RangeVarGetRelid() when a relation's rangevar is NULL, as
that function does not accept NULL input values.
