Re: Portal->commandTag as an enum

Thinking about this some more, would it be possible to treat these
like we do parser/kwlist.h? Something like this:

commandtag_list.h:
PG_COMMANDTAG(ALTER_ACCESS_METHOD, "ALTER ACCESS METHOD", true, false,
false, false)
...

then, just:

#define PG_COMMANDTAG(taglabel, tagname, event_trigger, table_rewrite,
display_rowcount, display_oid) label,

typedef enum CommandTag
{
#include "commandtag_list.h"
}

#undef PG_COMMANDTAG

...and then:

#define PG_COMMANDTAG(taglabel, tagname, event_trigger, table_rewrite,
display_rowcount, display_oid) \
{ tagname, event_trigger, table_rewrite, display_rowcount, display_oid },

const CommandTagBehavior tag_behavior[] =
{
#include "commandtag_list.h"
}

#undef PG_COMMANDTAG

I'm hand-waving a bit, and it doesn't have the flexibility of a .dat
file, but it's a whole lot simpler.
