0034072: Adding an index on c_bpartner_location.c_location will speed certain processes

DescriptionThere are processes that given a location (table c_location) they need to retrieve if it is related with any business partner location (table c_bpartner_location).

This results in the invokation of a query like this:

SELECT *
FROM c_bpartner_location
WHERE c_location_id = ?

In an environment with around 20 million entries in c_location and c_bpartner_location this query takes around 6 seconds. After adding an index in the column c_location of c_bpartner_location the query takes around 250 milliseconds (0000102:0000024 times faster).
Steps To ReproduceIn any database, invoke:

EXPLAIN SELECT *
FROM c_bpartner_location
WHERE c_location_id = <any_c_location_id>

Check that a sequencia scan is done in the c_bpartner_location table.

Fixes issue 34072: Adds an index to c_bpartner_location.c_location_id

The index will prevent sequencial scans on c_bpartner_location when a query like this is invoked:

SELECT *
FROM c_bpartner_location
WHERE c_location_id = ?

 The use case that benefited from the addition of this indexes was the following. There is a multiserver router (see [1]) that given a location it needs to obtain the list of servers that should receive changes done to that location.

As part of that process, the router needs to know if the modified location belongs to a business partner via the c_bpartner_location table (see [2]). It is a that point that the query mentioned in the issue description is invoked.
