SQL Query for Foreign constraint

[Bhim Kumar <bhimkumar33@xxxxxxxxx>]

Hi sir

Currently I am using following query on mysql :

* SHOW TABLES;   ---> To get list of table in a particular db.

* SELECT TABLE_NAME, CONSTRAINT_NAME, COLUMN_NAME, REFERENCED_TABLE_NAME, REFERENCED_COLUMN_NAME from information_schema.key_column_usage WHERE constraint_schema ='myDBName';

    --->  to get foreign constraint information.

* SHOW INDEX FROM myTableName FROM myDBName;

I am required to get above information from postgres.

I didn't find postgres query corresponding to above mysql query to fetch corresponding information.

PS : help me for above query in postgres.

Best Regards.

Bhim
