I'm not sure what "confiable" means...  The preferable version would be
the latest, namely rc4.

Based on the fact that rc4 has not seen any complaints, it seems likely
that it'll shortly become the true release.

Being NOTICE messages, these are clearly not errors.

Version 1.2 adds partial indexes on the disused sl_log_? table for all
origin nodes, which provides a faster and safer index which will be used
the next time Slony-I rotates between sl_log_1 and sl_log_2.  Being
partial, that means that the index makes for a clearly efficient way to
access data for a given origin node.  And since that index won't mix data
from multiple nodes, some of the concerns lurking about XID comparisons
should go away...

I don't imagine that the problem has anything to do with the notices
listed above; if you are looking for assistance with a problem, you'll
need to be more specific about what phenomenon you are experiencing.
