In addition to what Rodrigo said so eloquently in Portuguese (no fallu prtugues! <vbg>), the only issue you will experience is a performance hit.
It is not a good idea to have 2 separate database servers running on the same set of drive spindles. I usually deploy them in different servers. That way, the MS SQL Servr has priority access to the resources on the SQL Server box,, and the PostgreSQL on the PostgreSQL box. The other thing to take into account is that SQL Server needs lots of memory to operate, whereas from my experience PostgreSQL is a lot better with resources. Depending on the amount of memory on the box, PostgreSQl may not have enough left for it by SQL Server to run effectively.

Cara amiga brasileira! Como já respondido pelo Magnus, não tem absolutamente nenhum problema! Mas veja que se for um ambiente em produção isso pode gerar problemas futuros em relação ao desempenho!
Abraços!

Assunto: [ADMIN] Using PostgreSQL and MIcrosoft SQLServer on the same server
Good morning and greetings from Brazil!!
May anyone help me with a question...
I'm working on a project and we are supposed to use Microsoft SQLServer and PostgreSQL on the same server. There was any problem or risk on this? Anyone has worked on the same situation?
I searched on the web and on documentation and I could not find out comments about it.
Any help will be appreciated :)
