Table definition

[Bruno Prévost]

 

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.

Use pg_dump.

Not quite sure if this is quite what you're after, but would:

$ pg_dump -st foo

help at all? It gives out the SQL that you would need to enter to
re-create the table.

There is no direct way to do this in SQL, but I can offer you the following
alternative:

CREATE FUNCTION get_table_definition(text) RETURNS text AS '
#!/bin/sh
pg_dump -t $1
' LANGUAGE plsh;

:)

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.
