remove all murmur3-related source code. Alter regression tests
to reflect new hash values for inputs, and a slightly different
set of input data to ensure that sufficient chunks and partitions
are tested. Some changes to .sh scripts in sql/setup that seem
to be used only to power the "unit tests", which I cannot
yet run successfully.
Previously, each test set their own (although mostly the same)
configuration for log output and error verbosity. This is now set
globally in the test runner so that tests only need to set these
configuration parameters if they need to override the defaults. The
log verbosity is also reduced so that errors aren't generated with the
line number of the source file that output the error. Line numbers in
the output can break tests when upgrading to a new PostgreSQL version
that outputs a different line number.
- Directory structure now matches common practices
- Regression tests now run with pg_regress via the PGXS infrastructure.
- Unit tests do not integrate well with pg_regress and have to be run
separately.
- Docker functionality is separate from main Makefile. Run with
`make -f docker.mk` to build and `make -f docker.mk run` to run
the database in a container.
