lets have large table consists of 3 columns. integer id, timestamp ts, double value if wanted values given complicated date expression best way achieve ? for example if wanted values @ anytime on weekend days , between 18:00 , 8:00 on weekdays , time on school holidays year 2014. obviously of these times variable , solution should dynamic. thinking of storing series of date intervals things school holidays in table check against. however, create custom postgres function hide of complexity. does know of similar code or have suggestions ? dealing cases times above except on weekend logic ? thanks with holiday table select * t left join holiday on date_trunc('day', t.ts) = holiday.day extract(dow ts) in (0, 6) -- weekend or (extract(hour ts) >= 18 , extract(hour ts) <= 8) or holiday.day not null -- holiday
