Currently PostgreSQL doesn't have a function which gets TEXT and return true if it's valid email address (x...@yyy.com / .co.ZZ) Do you believe such function should exist in PostgreSQL or it's best to let every user to implement his own function?
I don't think so this functionality should be in upstream - but it is good use for some extension and placing it in PGXN or PostgreSQL community repository. Postgres has good regexp support and this case can be implemented by one regexp. you can use PLPerlu and use some modules from CPAN http://search.cpan.org/~rjbs/Email-Valid-1.202/lib/Email/Valid.pm <http://search.cpan.org/~rjbs/Email-Valid-1.202/lib/Email/Valid.pm> Regards Pavel In general, I see no reason for a modern RDBMS not to provide an email-datatype. IMV that's no different from other types which also could have been plain-text but are convenient to have datatypes for. Being an open-source project I guess one must show initiative and start a discussion on -hackers to see what interesst there's in having one in core. I for one hope there will be. -- Andreas Joseph Krogh CTO / Partner - Visena AS Mobile: +47 909 56 963 andr...@visena.com <mailto:andr...@visena.com> www.visena.com <https://www.visena.com> <https://www.visena.com>
