I know, but - off the top of my head - in most other lan-
guages "0abc" will then give a syntax error.

Especially if you consider such cases:
| tim=# SELECT 1D1; SELECT 1E1; SELECT 1F1;
| d1
| ----
| 1
| (1 Zeile)
| ?column?
| ----------
| 10
| (1 Zeile)
| f1
| ----
| 1
| (1 Zeile)
| tim=#
I don't think it's common to hit this, but the documentation
surely could use a caveat. I will write something up and
submit it to -docs.
Thanks,
Tim
