Yes, I know of two feats that are found in the D&D 3.5 book Complete Warrior. I am going to assume they are also okay to use in Pathfinder.
You can use melee weapons one size category larger than you
are with a -2 penalty on the attack roll, but the amount of effort it
takes you to use the weapon does not change. For instance, a Large
longsword (a one-handed weapon for a Large creature) is considered a
two-handed weapon for a Medium creature that does not have this feat.
For a Medium creature that has this feat, it is still considered a
one-handed weapon. You can wield a larger light weapon as a light
weapon, or a larger two-handed weapon in two hands. You cannot wield a
larger weapon in your off hand, and you cannot use this feat with a
Wield Oversized Weapon:
You can treat any weapon as if it were one size category smaller than
normal and one category "lighter" for the purpose of determining the
amount of effort it takes to wield. For instance, a halfl ing with
this feat could wield a Medium short sword as a Small light weapon, or
a human could wield an ogre's Large greatclub as a Medium twohanded
weapon. The weapon still deals its normal amount of damage.
I can't find the link right now - but these two feats do not stack so you have to choose which you want to apply.
Other than these two feats, I found that there have been multiple queries similar to yours about using oversized weapons in Pathfinder, and all of those have turned up with negative replies or suggestions to just use the two feats I posted above. There was one person who designed two feats but they aren't official. Officially Pathfinder does not have any feats directly dealing with this, but you should consult your DM if you plan to use content from D&D 3.0/3.5 or homebrew.
