commit    28972b6fc3dcd1296e844246b635eddfa29c38e1
Author:   Etsuro Fujita <efujita@postgresql.org>

    Add support for importing statistics from remote servers.
    
    Add a new FDW callback routine that allows importing remote statistics
    for a foreign table directly to the local server, instead of collecting
    statistics locally.  The new callback routine is called at the beginning
    of the ANALYZE operation on the table, and if the FDW failed to import
    the statistics, the existing callback routine is called on the table to
    collect statistics locally.
    
    Also implement this for postgres_fdw.  It is enabled by "restore_stats"
    option both at the server and table level.  Currently, it is the user's
    responsibility to ensure remote statistics to import are up-to-date, so
    the default is false.
