Running postgresql-10.5 on Slackware-14.2.
A table has a column defined as

In a .sql file to insert rows in this table psql has a problem when there's
no value for the next_contact column:
$ psql -f activities.sql -d bustrac psql:activities.sql:6: ERROR:
invalid input syntax for type date: ""
LINE 2: ...ise. Asked him to call.',''),
Explicitly replacing the blank field ('') with null is accepted. Why is
this?
Now I know to replace no dates with null I'll do so but I'm curious why
this
is needed.
Because:
invalid input syntax for type date: ""
means you are trying to enter an empty string("") and that:
a) Is not NULL
b) Is not a valid date string.
Thanks in advance,
