Обсуждение: pgsql: Refactor PinBufferForBlock() to remove checks about persistence.

Refactor PinBufferForBlock() to remove checks about persistence.

There are checks in PinBufferForBlock() function to set persistence of
the relation.  This function is called for each block in the relation.
Instead, set persistence of the relation before PinBufferForBlock().
