0037677: No need to check if ad_context_info table exists before creating it

DescriptionThe SessionInfo.initDB method creates the ad_context_info temporary table in postgres [1]. Before creating it, it consults the catalog to check if the table has already been created.

This method used to be called each time a connection was borrowed from the pool, but this behaviour changed in this issue [2], now it is invoked only when a physical connection is created in the database. This makes unnecessary to check if the temporary table has been created.

In a high concurrency environment, the query to check if the table exists took longer than 40 seconds, in a peak where lots of connections were created in a short time span.

[1] [^]
[2] [^]
Steps To Reproduce- Write log before this line [1], printing the result of the query. It will always return 0, making the query unnecessary.

Fixes issue 37677: Dont check if ad_context_info table exists before creating it

Now, if the pool is used, the query to check if the ad_context_info table already exists will not be done. This check can be skipped because
if the pool is used, the initDB method will only be called when a new physical connection is created, and in that case the temporary table is
garanteed not to exist.

This pool instance check is needed to keep supporting using pools other than org.openbravo.apachejdbcconnectionpool.JdbcExternalConnectionPool (or none at al),
but in those cases the query to check if the ad_context_info table exists will still be performed.
