Again, there is no auto index creation for foriegn keys. However if
you declared the column unique or its the pkey (ala unique) (As Scott
said) then there will an index.

No you cant turn it off because its how postgres enforces uniqueness
see http://www.postgresql.org/docs/8.1/interactive/index-unique-checks.html
for more

My guess, use the name of the index to try to distinguish. Auto
generated ones will always be in the form:
pkey: <table_name>_pkey(num)
unique: <table_name>_<column_name>_key(num)
