Description:
When loading a pivot table from a database, there is a 5-10 minute lag before getting the pop up that allows you to move the columns to the appropriate places. The table in question has around 25 data points and about 900 entries. It is being loaded over a LAN connection with a computer on the local network. The actual loading and refreshing of the table, however, only takes seconds. 

Steps to Reproduce:
1. Create and load a table in base. 
2. Put in any substantial amount of data points and entries. 20+ data points and 500+ entries.
3. Select to add a pivot table. 
4. Select the table from the database. 
5. Click okay. 

Actual Results:
Very long delay which causes LibreOffice to freeze up. After waiting 5-10 minutes, it finally loads.

Expected Results:
Relatively quick load time, given it should only be getting the table columns at that point. Again, the actual table loading once all of the columns are dropped into the pivot table happens in seconds.


Reproducible: Always


User Profile Reset: No

Additional Info:
Only happens with large tables. Small tables from the same database load the columns quickly, near instantaneous.
