pgproto3 DataRow.MarshalJSON will turn string which contains LF or VT into HEX string

[DengChan]

I'm developing a web pg client using pgproto3, but I found that when I using DataRow.MarshalJSON to parse the DataRow message, it will turn string which contains LF or VT into HEX string.

pgx/pgproto3/data_row.go

Lines 97 to 100 in 6f2ce92

	if b < 32 {
	hasNonPrintable = true
	break
	}

Because the ASCII of LF is 9 , and the ASCII of VT is 11.

But LF AND VT are often used in some text column.

Could we have some special treatment for these frequently-used ASCII ?

I don't think this can be changed at this point in a backwards compatible manner. I think you will need to wrap or rename the type to override the JSON logic.
