When I was writing my initial email I was remembering exactly this, my first basic programs.
I would like this feature more because I sometimes have a mess of triggers when this trigger function is fired on several tables and it needs to be the first on this table but not on that table. And usually trigger names have same names as their functions, so for this table I have to have a different name just to be fired first.
> This problem can raise ... there is a trigger foo using position 1, please > choose another
This is reminiscent of the old BASIC programming language, where you eventually learn to choose line numbers that aren't consecutive, so that if you later have to add lines in between you have some room to do so. (This happens when modifying a program sufficient times you are forced to renumber old lines where you want to add new lines that no longer fit in the sequence.) It's a pretty bad system.
In a computer system, alphabet letters are just a different way to present numbers, so you just choose ASCII letters that match what you want. You can use "AA_first_trigger", "BB_second_trigger", "AB_nope_this_is_second" and you'll be fine; you can do "AAB_oops_really_second" afterwards, and so on. The integer numbering system doesn't seem very useful/flexible when seen in this light.
