df3c6abf15 1) fix: Unique index must be complete used else we keep on looking for another one. 
2) MERGE can also handle expressions, stupid example :
  SELECT
    *
  FROM
    RDB$RELATIONS r,
    RDB$RELATION_FIELDS rf
  WHERE
    rf.RDB$RELATION_NAME || 'A' = r.RDB$RELATION_NAME || 'A'
3) Do some code style issues

b05dc24810 Forward port removal of artificial index number limitation from 1.0.3. 
Fix bug in dbb_max_idx calculation. Do not port GC and metadata versioning
changes as they seem very dangerous to me.

When an equal-node and other nodes (geq, leq, between...) are available for an index retrieval, then use the equal node always instead of the others.

52a7ba0d51 bugfix: a simple LEFT JOIN on a VIEW with only a ON clause didn't use an index even if it was possible.

fcb77779fa More and better optimizations with "complex" JOIN queries (LEFT JOIN, views, sp etc...). 
bugfix: An SORT can't be generated when there are already RSBs on the stack, because this will lead to strange values. See also SF BUG # [ 221921 ].
