This is just a cut from pg_dump and a paste into psql of the exact SQL
statement. I doubt pg_dump would get this wrong.

My understanding is that quote characters allow you to have fields with capital
letters and spaces, but using them unnecessarily is harmless.

fmfts=# CREATE TABLE contact_people (user_id character(30), account_id character(30), exchange_id character(30), isin_code character(30), symbol character(30), name character(30), position character(30), email_address character(30));
ERROR: parser: parse error at or near "position"

The plot thickens...

This is looking more and more like a bug in PostgreSQL's SQL parser.
