We'll need a bit more info before any viable advice can be given. How big is that polygon for the overlaps? Any error messages in the postgresql logs? Is there just one date's scenes in the table or is it longitudinal?

Hi bborie,
PostgreSQL crashed before showing any message. It run for about 600,000,000 ms then popup a window say "connection is lost". My raster's date is in range 15/04/2013 - 20/02/2014. By the way, I don't know how to query 1 date's scenes or 16-days scenes (The Landsat 8 satellite images the entire Earth every 16 days).
Here's my polygon:
ST_GeomFromText('POLYGON((105.78873 21.38659, 106.49185 21.38659, 105.78873 20.71758, 106.49185 20.71758, 105.78873 21.38659))', 4326)
Thank you!
-Jackie.
