Brian Cloutier e73b4ac026 Evaluate functions on the master
- Enables using VOLATILE functions (like nextval()) in INSERT queries
- Enables using STABLE functions (like now()) targetLists and joinTrees

UPDATE and INSERT can now contain non-immutable functions. INSERT can contain any kind of
expression, while UPDATE can contain any STABLE function, so long as a Var is not passed
into the STABLE function, even indirectly. UPDATE TagetEntry's can now also include Vars.

There's an exception, CASE/COALESCE statements may not contain mutable functions.

Functions calls in master_modify_multiple_shards are also evaluated.

Andres Freund 610e17d94a Combine router executor paths for select and modify commands.
The upcoming RETURNING support would otherwise require too much
duplication.  This contains most of the pieces required for RETURNING
support, except removing the planner checks and adjusting regression
test output.

Jason Petersen 518adff539 Minor formatting fix
Noticed that uncrustify doesn't like the array-of-struct literals, so
omitting them from formatting (at least here).

Jason Petersen f132dbad1a Use literal instead of constant to fix 9.4 build
PG_UINT32_MAX doesn't exist before 9.5. Missed this because I removed
my assert-enabled builds during packaging work.

Fixes #619

Amos Bird b58dfd93ae Add overflow checks. 2016-06-08 10:30:03 +08:00
Amos Bird ad42423c24 Eliminates the possibilities of counter overflows.
This patch uses scanint8 instead of pg_atoi to make sure the affected
tuples counter never gets overflow.

Jason Petersen 8efb504d1a Refactor ReportRemoteError to remove boolean arg
Broke it into two explicitly-named functions instead: WarnRemoteError
and ReraiseRemoteError.

Murat Tuncer 2bc96fabe5 Add dynamic executor selection
- non-router plannable queries can be executed
  by router executor if they satisfy the criteria
- router executor is removed from configuration,
  now task executor can not be set to router
- removed some tests that error out for router executor

Ensure router executor acquires proper shard lock

Jason Petersen 130e65f5be Ensure router executor acquires proper shard lock
Though Citus' Task struct has a shardId field, it doesn't have the same
semantics as the one previously used in pg_shard code. The analogous
field in the Citus Task is anchorShardId. I've also added an argument
check to the relevant locking function to catch future locking attempts
which pass an invalid argument.

Jason Petersen 166f96bb83 First formatting attempt
Skipped csql, ruleutils, readfuncs, and functions obviously copied from
PostgreSQL. Seeing how this looks, then continuing.

Jason Petersen f2bf7fc802 Rename GetConnection to address name conflict
The postgres_fdw extension has an extern function with an identical
signature, which can cause problems when both extensions are loaded.
A simple rename can fix this for now (this is the only function with)
such a conflict.
