hi Melvin, appreciate the reminder. Our issue is that we have 300+
columns and frequently include them in the SELECT or WHERE clauses... so
traditional normalization would involve hundreds of joins.
That's why I ask about a new table or column type that handles basic
translation and de-duping transparently, keeping the coded values
in-table.

AFAIK, there is no such thing currently available.Your initial post indicated you were working with spreadsheets and were
looking to translate to PostgreSQL database. There is no short cut to normalizing, but the time you spend doing so in initial
design will well be worthwhile once it is implemented.
