It turns out i have been **years** doing this wrong: you are supposed to
pass that value as a text, like 'CURRENT_TIMESTAMP', not like the
keyword so that it returns the current timestamp as a timestamptz.
However, i have been doing it wrong because of a bug in previous
versions of pgTAP[0], that did not take into account keywords such as
CURRENT_TIMESTAMP or CURRENT_DATE and was comparing their actual values,
not the names, therefore i thought that i misread the documentation.
Only now have discovered this because Debian 12 upgraded pgTAP version
to 1.2.0.

They are mostly the same as invoices, but the contact and payment method
are optional, thus, like other optionals fields, i created relations to
link these that have payment method or contact, to avoid NULL columns in
quote.
Still missing functions to add and edit quotations, and views to compute
their tax and total amount.
