Adds support for PostgreSQL 10 by copying in the requisite ruleutils
and updating all API usages to conform with changes in PostgreSQL 10.
Most changes are fairly minor but they are numerous. One particular
obstacle was the change in \d behavior in PostgreSQL 10's psql; I had
to add SQL implementations (views, mostly) to mimic the pre-10 output.
With this commit, we start to use custom compiled PostgreSQL builds in
Travis for merge commits. This allows us to run isolation tests and
PostgreSQL's own regression tests along with our regression tests in
Travis.
Since manually compiling PostgreSQL takes more time and we also add new
tests, we only enable running these tests on merge commits.
Not that this is not with the citus *extension* loaded, just the shared
library. The former runs (by adding --use-existing to the flags) but
has a bunch of trivial test differences.
On some systems a new libpq is available than what we're compiling
against, but until now we used psql in the version we're compiling
against. That' a problem, because (quoting Jason):
With 9.6, libpq's default handling of CONTEXT changed: it is hidden
unless the level is ERROR or higher. We addressed this ourselves using
the SHOW_CONTEXT variable (by setting "always" in pg_regress_multi): in
9.5, this is ignored (and unneeded), in 9.6, it ensures old behavior is
preserved.
For 9.6 we'd already worked around the problem by specifying that
context should always be shown, but < 9.6 psql doesn't know how to do
that.
As there's no csql anymore, which strictly tied us to a specific version
of psql/csql, we can now just use the system's psql if available. We
still fall back to the psql of the installation we're compiling against,
if there's no other psql in PATH.
Adds support for PostgreSQL 9.6 by copying in the requisite ruleutils
file and refactoring the out/readfuncs code to flexibly support the
old-style copy/pasted out/readfuncs (prior to 9.6) or use extensible
node APIs (in 9.6 and higher).
Most version-specific code within this change is only needed to set new
fields in the AggRef nodes we build for aggregations. Version-specific
test output files were added in certain cases, though in most they were
not necessary. Each such file begins by e.g. printing the major version
in order to clarify its purpose.
The comment atop citus_nodes.h details how to add support for new nodes
for when that becomes necessary.
Related to #786
This change adds the `pg_dist_node` table that contains the information
about the workers in the cluster, replacing the previously used
`pg_worker_list.conf` file (or the one specified with `citus.worker_list_file`).
Upon update, `pg_worker_list.conf` file is read and `pg_dist_node` table is
populated with the file's content. After that, `pg_worker_list.conf` file
is renamed to `pg_worker_list.conf.obsolete`
For adding and removing nodes, the change also includes two new UDFs:
`master_add_node` and `master_remove_node`, which require superuser
permissions.
'citus.worker_list_file' guc is kept for update purposes but not used after the
update is finished.

With this change we schema-prefix table names, operator names and composite types.
-Added 2 more schedules for task-tracker and multi-binary
instead of running multi_schedule 3 times
-set task-tracker-delay for each long running schedule
Fixes#10
This change creates a new UDF: master_modify_multiple_shards
Parameters:
modify_query: A simple DELETE or UPDATE query as a string.
The UDF is similar to the existing master_apply_delete_command UDF.
Basically, given the modify query, it prunes the shard list, re-constructs
the query for each shard and sends the query to the placements.
Depending on the value of citus.multi_shard_commit_protocol, the commit
can be done in one-phase or two-phase manner.
Limitations:
* It cannot be called inside a transaction block
* It only be called with simple operator expressions (like Single Shard Modify)
Sample Usage:
```
SELECT master_modify_multiple_shards(
'DELETE FROM customer_delete_protocol WHERE c_custkey > 500 AND c_custkey < 500');
```
Otherwise the owner of relations and such will depend on the username of
the user running the regression tests. As "postgres" is the most common
username for that purpose, hardcode that in pg_regress_multi.pl.
There already exist tests that locally embed knowledge about port
numbers, and there's more tests requiring that. Instead of copying
\set's to several tests, make these port number variables available to
all tests.
All citusdb references in
- extension, binary names
- file headers
- all configuration name prefixes
- error/warning messages
- some functions names
- regression tests
are changed to be citus.
