convenience function to stand in for `.inspect`?

[pskrbasu]

Could do this in steampipe_postgres_fdw_github--1.0.sql

drop function if exists steampipe_fdw_schema
create function steampipe_fdw_schema(schema text, table_name text) returns table (
  column_name_and_type text
  ) as $$
  select distinct
    column_name || ': ' || data_type as column_name_and_type
  from 
    information_schema.columns 
  where 
    table_name = table_name and
    table_schema = schema
  order by
    column_name_and_type
$$ language sql;

then:

select steampipe_fdw_schema('github', 'github_issue');

                  steampipe_fdw_schema
----------------------------------------------------------
 _ctx: jsonb
 action: text
 active_lock_reason: text
 actor: jsonb
 actor: text
 actor_location: jsonb
 actor_login: text
 additions: bigint
 affiliation: text
 alert_number: bigint
 allow_update_branch: boolean

Much nicer than looking up and using some version of the underlying query.
