Annex Status: Draft<br />
PostgreSQL provides the standard SQL type boolean. boolean can have one of only two<br />
states: "true" or "false". A third state, "unknown", is represented by the SQL NULL value.<br />
Valid literal values for the "true" state are:<br />
TRUE<br />
't'<br />
'true'<br />
'y'<br />
'yes'<br />
'1'<br />
For the "false" state, the following values can be used:<br />
FALSE<br />
'f'<br />
'false'<br />
'n'<br />
'no'<br />
'0'<br />
Using the key words TRUE and FALSE is preferred (and SQL-compliant).<br />
