Heikki Linnakangas 4ebd740cd3 Fix snapshot reference leak if lo_export fails. ... If lo_export() fails to open the target file or to write to it, it leaks the created LargeObjectDesc and its snapshot in the top-transaction context and resource owner. That's pretty harmless, it's a small leak after all, but it gives the user a "Snapshot reference leak" warning. Fix by using a short-lived memory context and no resource owner for transient LargeObjectDescs that are opened and closed within one function call. The leak is easiest to reproduce with lo_export() on a directory that doesn't exist, but in principle the other lo_* functions could also fail. Backpatch to all supported versions.
