BUG #14903: problem with bool array

"The array subscript numbers are written within square brackets. By
default PostgreSQL uses a one-based numbering convention for arrays,
that is, an array of n elements starts with array[1] and ends with
array[n]."

Bug reference: 14903
Logged by: Roman Morozov
Email address: arclight1995@gmail.com
PostgreSQL version: 9.6.5
Operating system: PostgreSQL 9.6.5 on x86_64-pc-linux-gnu, compiled
Description:

1) set value for field with type bool array:
update "ContractorImage"
set "States" =
'{f,f,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}'
2) try to change first value of array:
update "ContractorImage" set "States"[0] = true

3) instead of '{t,f,null,...}' it becomes '{t,f,f,null,...}'. why doesd
first element have index 1 instead of 0 ?
