I will strongly recommend removing the quotes around table name and column
names. Else you may have challenges porting application to PG. As PG by
default refers to object names in small case unless you out quotes around
them.

So after migration a statement like

Select * from DLR_FAM_MRKTSHR_FY_END;

would fail.

Also about the error, see what is before this create table statement. Make
sure there is a semi colon to terminate the statement before the CREATE
table.

How are you running it? psql?
