Add auto VACUUM+ANALYZE settings to Postgres Database

[justb4]

Performance on a PG database tables with millions of records can significantly improved by regularly VACUUM-ing tables. See this article here:

When checking the last time tables are vacuumed in a schema, it appears some of the larger tables were not vacummed/analyzed at all!

SELECT relname, last_vacuum, last_autovacuum, last_analyze, last_autoanalyze  
FROM pg_stat_all_tables  
WHERE schemaname = 'smartem_refined';

result for refined data (now 8 million records in timeseries table):

and for GOST data:

This seems to be urgent. A request to /Observations no longer returns:
