Обсуждение: Problem with alter table (creating a foreing key post facto)

A curious problem with 7.3.1 : I wanted to add a foreing key constraint to
a table already created and populated. No way, according to Postgres :

essai=# alter table tableb add constraint lien_a_a foreing key (refa)
references tablea (keya);
ERROR:  parser: parse error at or near "foreing" at character 44
essai=# alter table tableb add foreing key (refa) references tablea (keya);
ERROR:  parser: parse error at or near "(" at character 36

WTF ????

Any ideas ?

Sincerely,

It helps if you spell foreign correctly. ;)

[ Feeling *very* silly ... ] Apologies ! English not being my mother
tongue, I overlooked this (although I checked lots of time before
helling for help ...).
