commit 8cb32febe56d62b986598cdad0ae66aeffeb1f63
Author: Ashutosh Bapat <ash...@en...>

Push LIMIT clause to the datanode if the expressions in those
clauses are shippable and the underlying plan tree allows that.
In case there is only one datanode involved in the execution of the RemoteQuery,
we just push the clause to the datanode and no LIMIT and OFFSET processing is required at
the coordinator. But for distributed execution of RemoteQuery, we need LIMIT and
OFFSET processing at the coordinator.
If OFFSET clause is present, we do not push it, but include it in the LIMIT
clause and apply OFFSET at the coordinator.

commit 16992e6b07d28d66c183adf45dd8e1cae2cdf25b

Move GTM configuration APIs in src/gtm/common to new folder src/gtm/config
This is part of the effort to eliminate the duplications in GTM code with things
of PG src/backend. src/gtm/common had a dependency with the binary postgres when
it is built so this dependency with GTM configuration is unnecessary. Even if
GTM should rely on the APIs of guc-file.l for configuration file treatment, for
the time being this permits to split each functionality correctly.
