My Master postgres db is currently < 100 mb.
I am doing the initial replication on another machine, using command
pg_basebackup -h 'masters_ip' -D /1TBdisk/postgres/ -U replica -v -P
But its going very slow, and appears to be downloading a huge tablespace (100172766 kb ~= 95 GB ).
Not sure what's going on there. It will eventually complete overnight, but I'd really like to know why the tablespace is close to 95 gb.
