So exactly what is the order of casts that produces different results with: 'x' || ' ' || 'x' and 'x' || ' '::char15 || 'x' Are operators being invoked both (text,text)? I'm trying to understand the precedence that causes the different results. elein On Tue, Feb 17, 2004 at 10:53:17PM -0500, Tom Lane wrote: > elein <elein@varlena.com> writes: > > Apparently the ::char is cast to varchar and then text? > > No, directly to text, because the || operator is defined as taking text > inputs.
