 revision="a4ecc46176c3fc0ab3fa69cf117d408bc622e592"
 doc: correct ST_BandIsNoData forceChecking default

 The SQL signature defaults forceChecking to false, and the function
 description already says the default is false. Align the synopsis so users
 looking for the cheap metadata path do not see the expensive forced scan
 advertised as the default.

 Closes https://github.com/postgis/postgis/pull/977
