error message: operator does not exist: integer = character varying
The error's resean is just as the error message said, and i known this can be avoided by set stringtype=unspecified in url. But i still have two question。
1)when stringtype is setted to be "unspecified",is there any bad think would happen?
2)If the answer of 1)is "nothing",why pgjdbc not setting the default value of stringtype to "unspecified"
