Link targets used in the downstream documentation were removed from the Oracle, PG, and SQL Server connector docs, leading to failures when building the downstream docs.

• Oracle: The former Behavior when things go wrong topic and the associated anchor link were removed and replaced by an FAQ topic, causing a cross reference on L51 that was conditionalized for [product] use to fail. Replace the link target to point to the new oracle-frequently-asked-questions anchor.
• PG: Removal of the Meta information topic that was present in 1.9 and earlier breaks the [product]-conditionalized link on L109.
• SQL Server: L2142 The database.names property was conditionalized as community-only content. Because a link from the description of the tasks.max property targets database.names, it must likewise be conditionalized.

The preceding changes do not effect the community version of the documentation.
