Attached are docs that add the new syntax, and mention it is
non-standard; you can see the output here:

We do document three syntaxes for substring() in the same table, one row
for each, so there is precedent for doing this.
Attached is an updated patch with a proper example. I could move the
extra syntax into the description of the existing trim entry instead.
Patch applied to head. I did not apply this to 9.3 in case we change
our minds about documenting this.
