hi, The implements of 'xidin' use only ‘strtoul’ to cast from string to xid. So in some cases, may cause confusion, for example, The sql 'select c1 from test where xmin='abc' can be executed. and sometimes will make mistakes, I want to query "select c1 from test where xmin='0x10'" ,but write 'Ox10', '0' to 'O',The result is obviously wrong.
The patch will correct it. I have justly copy some code of 'OID'. Whether we need to extract the common code?
