dblink performance

Hello All,

I'm currently on a development team utilizing PostgreSQL and we are
looking into the possibility of using dblink to reference an external
database (read only). Our system administrator and DBA were concerned
about the performance impact that cross-database queries would have on a
production application. Are there any known performance issues or
anything of the like that I would need to know before pushing this issue
further? I have been using PostgreSQL for the past couple months but
this is my first time using dblink. I really just need an opinion from
someone who has used this technology before. Thanks!
