Обсуждение: Table definition
Hi,
Anybody know how to obtain the table definition in text.
Something like "select definition from pg_catalog.pg_views where viewname = 'xxx'" but for a table.
Thanks
Bruno
Probably there is no direct way get the definition (i could not find one atleast).
You can probably write a custom function which gives all columns, indexes and formulate a create table statement (text definition).
Let us know if you find a way out.

It could help me, but pg_dump give all foreigns key and index creation. I'm not sure if it's not better to write a custom function in plpgsql.
