postgresql on schema update

Hi all the people, 

using cakephp 2.3.4 when i update my schema table using postgresql 9.2 i'm getting this error:

Updating Database...

reports: SQLSTATE[42601]: Syntax error: 7 ERROR:  error de sintaxis en o cerca de «,»

LINE 14:  ALTER COLUMN "tableParameters" TYPE ,

Is possible that postgresql datasource was incomplete or wrong for tableParameters fields structure?

Thank you very much.
