In postgresql is stored as a bit, not numbers, chars or strings. The
"true/false" is just a representation for input, which are many
alternatives, as postgresql doc says:
Valid literal values for the "true" state are:
TRUE
't'
'true'
'y'
'yes'
'1'
For the "false" state, the following values can be used:
FALSE
'f'
'false'
'n'
'no'
'0'
However, that '0' and '1' are read as chars/strings, that is with ""
or '' which the ["#{column.search_sql} = ?", value.to_i] skips.
