Re: Re: Unterminated quoted string error. - Mailing list pgsql-jdbc

Thomas,

You are correct about the poor documentation for bytea.  I hear this is

looking at the internal pg_* tables and seeing how they used it.

I'm glad to hear that you have a workaround for your original issue.

thanks,
--Barry
