The alterations done upon postgresql.conf with 512 RAM were these:

max_connections = 3
shared_buffers = 6000
wal_buffers = 32
sort_mem = 2048
fsync = false
effective_cache_size = 44800
random_page_cost = 3
default_statistics_target = 50

Yes I have an index on actvars.product_level and an index on
prodlevel.code_level.Both indices have character(12) data types.
