There’s nothing special about the postgres database, drop it and see. The system information lives in system catalogs that are not attached to any particular database. The template0 and template1 databases are “special” in that new databases are created by copying the contents of those templates, so alterations to them will percolate into any new databases created, so they should generally be left alone (unless you have a reason to want something included in all new databases). If you drop template1 you will find it hard to create new databases (unless you specify a different template) but otherwise things will keep running.<div class=""><br class=""></div><div class="">Anyways, I imagine the mystery of the Esri connection to ‘postgres’ is just that someone at Esri thought the same as you, seeing that most builds of postgres do ship with a postgres database already created, so that the postgres database user can easily have something to connect to that is not one of the templates.

That’s what I’m talking about. when I first tried to connect to Posters (and the “postgres” named database, I kept getting an error from ArcGIS saying the the “postgres” name for a database was a bad thing, and it wouldn’t connect. After much searching, I
discover that the name, “postgres” for a database wasn’t allowed by the ArcGIS client to connect to.

<div class="">I had to dig fairly deeply into the ESRI site to find this particular explanation for why the service couldn’t/wouldn’t get connected. Just to be clear, we do use logins for accessing the database, we just have chosen to use the “postgres” (named)
database.

<div class="">All,

<div class="">One biggie, is that the ESRI side does not like connecting to the “postgres” named database, claiming it’s a System database (whatever that means). This is not readily available as a limitation either when looking for reasons why it won’t connect.
We’ve been using the “postgres” database name for years (a decade now??) with no ill effects from other applications/ connections. I sort of understand this from the commercial side having worked with other databases like Oracle and MSSQL, but still, there
should be a way to side step this with a setting somewhere.
<div class=""><br class="">
</div>
<div class="">I looked high and low for a way to alias the “postgres” database name inside of Postgres, but didn’t find anything very easy to implement or maintain very easily. I did think about setting up another dataabase and using Views to the postgres
database, but that seemed like a bad idea for some reason, along with being somewhat hard to maintain, but upon reflection I keep coming back to the idea.</div>
<div class=""><br class="">
</div>
<div class="">All non “postgres” named connections seem to work fine so far. Haven’t implemented anything yet that is really heavy duty as far as loading though, so who knows.</div>
<div class=""><br class="">
</div>
<div class="">Anyway, just my 2cents.</div>
