--- Tests for the planner's "equivalence class" mechanism
---
--- One thing that's not tested well during normal querying is the logic
--- for handling "broken" ECs. This is because an EC can only become broken
--- if its underlying btree operator family doesn't include a complete set
--- of cross-type equality operators. There are not (and should not be)
--- any such families built into Postgres; so we have to hack things up
--- to create one. We do this by making two alias types that are really
--- int8 (so we need no new C code) and adding only some operators for them
--- into the standard integer_ops opfamily.

--- PLPGSQL
---
--- Scenario:
---
--- A building with a modern TP cable installation where any
--- of the wall connectors can be used to plug in phones,
--- ethernet interfaces or local office hubs. The backside
--- of the wall connectors is wired to one of several patch-
--- fields in the building.
---
--- In the patchfields, there are hubs and all the slots
--- representing the wall connectors. In addition there are
--- slots that can represent a phone line from the central
--- phone system.
---
--- Triggers ensure consistency of the patching information.
---
--- Functions are used to build up powerful views that let
--- you look behind the wall when looking at a patchfield
--- or into a room.

-The waves beside them danced; but they

-A poet could not but be gay,
-In such a jocund company:
-I gazed--and gazed--but little thought
-What wealth the show to me had brought:
-
-For oft, when on my couch I lie
-In vacant or in pensive mood,
-They flash upon that inward eye
-Which is the bliss of solitude;
-And then my heart with pleasure fills,
-And dances with the daffodils.
