fix: SQL queries to improve Postgres support

Noticed an issue when get_single_value wasn't returning the correct
values; by converting true to 0.

Tested it out. Here's the examples:

In [2]: sbool("2")
Out[2]: '2'

In [3]: cint(sbool("2"))
Out[3]: 2

In [4]: cint(sbool("-1"))
Out[4]: -1

In [5]: cint(sbool("0"))
Out[5]: 0

In [6]: cint(sbool("1000"))
Out[6]: 1000

In [7]: cint(sbool("10_000"))
Out[7]: 10000

In [8]: cint(sbool("true"))
Out[8]: 1
