How to limit what table/function/trigger options in the pop-up, when using the '.' (period) function

I've just connected to Heidi to Postgres for a project I am working on.

My issues is this; when I use the schema_name with the '.' function to bring up the selection of tables/columns (one of my favourite features of Heidi), it brings up (in addition to all the tables that I want) ALL The functions, triggers, views, events etc. This didn't happen when using Heidi with MYSQL database.

Due to the spatial nature of my data and Postgres (Postgis) setup, this is an awful lot of data to read each time, and takes a good 10 seconds to pull up the whole list.

Is there a way to enable JUST the tables (ignoring all functions and triggers etc)?
10 seconds isn't terribly long, but this is at the beginning of my project and the data is likely to grow, and so will the tables, making this issue more time consuming in future.

any thoughts on this?
