Hello again,
Reading a previous recent post and answers called "Describe Table"
got me thinking about a little piece of SQL I use in an application
to get a list of all the tables for a specific namespace:
select pg_class.relname as table_name
from pg_class
join pg_namespace on pg_namespace.oid = relnamespace
where pg_class.relkind = 'r' and pg_namespace.nspname = 'public'
order by pg_class.relname
I have assumed that this sort of query would be relatively
"durable" - that future system catalog changes are unlikely to make
this query stop working? Does anyone have any knowledge of how
"fixed" the columns and values of this query are (i.e. are there a
lot of internal and external dependencies that make future Pg
versiosn unlikely to break the above code)?
Any other input on the above SQL - should I be doing this in
another way?
Thanks for any thoughts or advice,
If all you're looking for is regular tables, the I'd use the
pg_tables view.
