anywhere from zero to two TODO items. * Allow flag to control COPY input/output of NULLs I got this: COPY table .... [ WITH NULL AS 'string' ] which does what you'd expect. The default is \N, otherwise you can use empty strings, etc. On Copy In this acts like a filter: every data item that looks like 'string' becomes a NULL. Pretty straightforward. This also seems to be related to * Make postgres user have a password by default If I recall this discussion correctly, the problem was actually that the default password for the postgres (or any) user is in fact "\N", because of the way copy is used. With this change, the file pg_pwd is copied out with nulls as empty strings, so if someone doesn't have a password, the password is just '', which one would expect from a new account. I don't think anyone really wants a hard-coded default password. Peter Eisentraut Sernanders väg 10:115 |
