The following documentation comment has been logged on the website:

Description:

Foreign tables are analyzed only when explicitly selected.  

Nothing wrong just maybe my newness to PG.   I don't understand what
"selected" means here: 
1. When I select the table in a query
2. When I run the analyze command with the FDW table as a parameter
3. Or something else

Also, I am not clear if analyze is run on FDW tables when Automvacuum runs;
does it run analyze on FDW tables by default.

Thanks,
Leon
