Describe the bug
killed
To Reproduce
run ether_sql --settings='PersonalGethSettings' scrape_block_range --start_block_number 6305955 , my eth light geth node is syncing and it's over block 6305955

but, i get killed when i try to push data in database

i get killed too if i use same command with infura: ether_sql --settings='PersonalInfuraSettings' scrape_block_range --start_block_number 6305955

i've modified settings.py like that:

but, if i do ether_sql scrape_block --block_number 6305955 it also connect to DefaultSettings(infura, not my api ) and it works

Expected behavior
to not get killed and to push blocks into database
