PostgreSQL Cluster
PostgreSQL 9.6.5 on x86_64-pc-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit

What is happening:

1. Right click on a table in the object browser
2. Select Scripts
3. Pick any of the following:
* INSERT Script
* SELECT Script
* UPDATE Script
4. A new tab opens with spinning wait wheel
5. When the spinning wheel clears the text editor is empty

Note: the CREATE and DELETE script properly load

What is expected:
The new tab should populate with the appropriate SQL.
