Index name collision

[Jeff Lowery]

[ProductStoreContactMechPurpose]: SQL Exception while executing the following:
     [java] CREATE INDEX PRT_CNT_MCH_PRS_TP ON 
public.PRODUCT_STORE_CONTACT_MECH_PURPOSE (LAST_UPDATED_TX_STAMP)
     [java] Error was: org.postgresql.util.PSQLException: ERROR: relation 
"prt_cnt_mch_prs_tp" already exists

Is this a generated index name?  I can't find it in any entity files.  What 
would be the best way to change it?
