Here vacuum_mem is too high, memory wasted, if you do
regular vacuum or you use the autovacuum daemon then
usualy 32MB are enough

you didn't show us the result of

vacuum full verbose


so I can not tell you if they are enough or not.

Do you think that an index scan is always worst then a seqscan ?

decrease this value to 2.5

I suggest you to start the collectors

stats_start_collector = true
stats_command_string = true
stats_block_level = true
stats_row_level = true
stats_reset_on_server_start = false
