This is a broad question. The permanent resident cannot grant you immediate benefit. Therfore, if you are in the US, you will not be able to file for adjustment of status until you become a US citizen. If you are outside US, it will be recommended to wait unless you can enter on a dual intent visa.
Talk to a good immigration lawyer before you decide.

In general, a Lawful Permanent Resident (holder of a "Green Card") may petition for a spouse in the Family-based Second Preference category, for which visas currently are available for spouses from most countries in cases filed in March, 2006 or earlier. As you can see, there is a backlog for visas in this category that can last several years, and therefore the spouse would need to explore eligibility for other immigration benefits during the waiting period, or would need to wait outside the U.S.
If the Green Card holder becomes a U.S. citizen, then generally the citizen can petition for a spouse in the "Immediate Relative" category, for which there is no visa backlog.
If someone were to marry a Green Card holder in August, a Petition for Alien Relative could be filed right away in the Second Preference category, and upon the Green Card holder becoming a citizen, the case would shift to the Immediate Relative category so that the spouse could apply for Adjustment of Status, with an Employment Authorization Document ("EAD" or "work permit") issued while the Adjustment of Status case is pending.
