Does anybody know where in the specification it details the required/acceptable conversions from string values to boolean? I cannot seem to find it in the PDF for 4.2.
I am curious about some of the conversions that are done. For example, calling “ResultSet.getBoolean” on a text/varchar column with the value “1.0”. This conversion succeeds because the driver (both pgjdbc & ng) fallback to decoding the column as a double then converting that by testing it “== 1”; which seems valid but questionable since “!= 0” would also be valid, but vastly different.
This is not allowed by Postgres (e.g. “SELECT “1.0”::bool;” results in an error) and I cannot find anything in JDBC as of yet.
