This link provides the list of available domain operators. http://stackoverflow.com/a/29443027
Are there operators to perform the following:
Matches beginning of the string word only
Matches end of the string only
Matches beginning of the word only
Matches end of the word only
NB: There are operators in Postgresql to perform the same. Like \A, ^, \M,\m,\Y,\y,\Z
Thanks!
