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)
This polygon is an invalid bow-tie, with a self-intersection in the centre.

Hi Mike,
It's my mistake. I swapped point No. 3 and point No. 4 and now the
message is "out of memory"
Besides, I can get the result with one band, but when I try to merge 3
bands, it fails.
ST_GeomFromText('POLYGON((105.78873 21.38659, 106.49185 21.38659,
106.49185 20.71758, 105.78873 20.71758, 105.78873 21.38659))', 4326)
