Hi There, I am new to Postgresql. I have few questions regarding the sql syntax in Postgresql. 1. I am trying to disable constraints from a particular table in postgresql. But I couldn't get the alter command for the same. 2. I am trying to fetch all the constraints from a specific table using a select query. I am using 'select * from pg_constraint'. If I execute this query I am able to get all the constraints from all the tables. But I couldn't find which constraint is for what table. How can I get this data. 3. I am also trying to fetch all the triggers for a specific table using a select query. How can I get this data? 4. I also would like to know how can I execute an sql file from windows command prompt in postgresql. Please help me with these details.
