I now remember a new problem with this feature, irregardless of whether
we use 'lc_messages' or 'lc_time'.
The problem is having a function's output affected by a GUC variable.
If you create an expression index using the function, and later query
the index with a different GUC value, or you do inserts with different
GUC values, the index will not work.
I know we have had this problem in the past, but I can't remember if or
how we addressed it.
