comment Method to translate PgRouting to ESRI Network Analyst network dataset?
Well, source and target attribute of pgRouting are not an innate part of a PostgreSQL table either. It's just an integer column, so you won't lose any information. There is PostGIS Topology as well, but I wouldn't use it for pgRouting.

While I have no knowledge about ArcGIS, why do you say exporting to SHP file does not preserve topology? In pgRouting topology is simply the source and target column, so when you export the table you don't lose this information. It's another question, if ArcGIS can make use of these attributes or not, but someone else needs to answer this.

I can't see the relation to pgRouting, so the tag is misleading and needs to be removed.

comment How to make a routable network topology?
With multilinestrings pgRouting will not work correctly. Because there is only a single source and target attribute and you will get strange results as pgRouting will only take the first linestring of the multilinestring record. See gis.stackexchange.com/questions/116414/…

comment pgRouting. pgr_ksp() returns -1 as id3
Which version of pgRouting do you use? Because there was just recently a change, which was merged into "develop" branch but the documentation might be not updated yet.
