pgsql: Make RangeTblEntry dump order consistent

Make RangeTblEntry dump order consistent

Put the fields alias and eref earlier in the struct, so that it
matches the order in _outRangeTblEntry()/_readRangeTblEntry(). This
helps if we ever want to fully automate out/read of RangeTblEntry.
Also, it makes dumps in the debugger easier to read in the same way.
Internally, this makes no difference.
