I want to write a selectivity function for GIST
indexes. The select condition is somefield &&
array[1,2,3], But when I’m inside selectivity function I get
args: T_Var, T_Const. So function needs to get the actual array contents
from T_Const . How to do it ? P.S T_Const is like $18 = {xpr = {type = T_Const}, consttype = 1007,
constlen = -1, constvalue = 138884428, constisnull = 0 '\0', constbyval = 0 '\0'} Thank you! |
