INSERT doesn't like (

Adam Levine (adam_l_levine@hotmail.com) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
INSERT doesn't like  (<table>.<column>)

Long Description
I'm using Dynamo connected to Postgres.  The PreparedStatement generated for an INSERT works on other dbs, but Postgres
complainswith a parsing error. 
 specifically:
   INSERT into <table> (<table>.<column>) VALUES (<value>);

it will, however, accept:
   INSERT into <table> (<column>) VALUES (<value>);

I tested against SQL-Anywhere, just to make sure I wasn't losing my mind, and it takes either form.

This is using postgres 7.0.2.

What's your definition of "other dbs"?  The above statement is quite
clearly in violation of the SQL92 and SQL99 specifications:

         <insert statement> ::=
              INSERT INTO <table name>
                <insert columns and source>

         <insert columns and source> ::=
                [ <left paren> <insert column list> <right paren> ]
              <query expression>
              | DEFAULT VALUES

         <insert column list> ::= <column name list>

         <column name list> ::=
              <column name> [ { <comma> <column name> }... ]

         <column name> ::= <identifier>

I'm not particularly excited about supporting non-SQL variant syntaxes
that add no functionality.

This isn't allowed by SQL and is completely useless.

         <insert statement> ::=
              INSERT INTO <insertion target>
                <insert columns and source>

         <insertion target> ::=
              <table name>

         <insert columns and source> ::=
                <from subquery>
              | <from constructor>
              | <from default>

         <from constructor> ::=
              [ <left paren> <insert column list> <right paren> ]
                [ <override clause> ]
                <contextually typed table value constructor>

         <insert column list> ::= <column name list>

         <column name list> ::=
              <column name> [ { <comma> <column name> }... ]

         <column name> ::=
                <identifier>
