Обсуждение: fmgr cache lookup failed on initdb
Hello, I have ported PostgreSQL to the AmigaOS using a Unix emulation library. PostgreSQL 6.1 work fine but either PostgreSQL 6.2 and 6.4.2 give me problems on initdb. Postgres backend spits out this message: ERROR: fmgr_info: function 0: cache lookup failed Anybody has any idea of why this happens? BTW, since the Amiga Developer environment that I used emulates the normal Unix enviroment, would the PostgreSQL developers be interested that integrated any Amiga specific templates and ported code to make the main distribuition of PostgreSQL build out of the box on the Amiga OS too?

Definitely...please send patches in to pgsql-patches@postgresql.org with
what is required, but plesae make sure that any patches are against the
current source tree, not v6.4.2...

Ok, but to work on the current source tree wouldn't it be better to get me a CVS write account so I can work in the absolutely latest version? Don't worry I have plenty of experience to deal CVS issues. I have all my current projects in CVS repositories and a few of them are shared by other people on the Internet. If you still don't feel it is safe I could always set a separate branch to integrate my changes before anybody commits into the main branch. Anyway, I still would like to make sure that the backend works without the cache lookup problems mentioned above. Do you know if that was fixed in the current source tree?

Access to the CVS repository is limited, with the only ones that have
received it in the past being those that have worked with us for ages now,
and have proven themselves in so far as the patches they have submitted.
There is access to the current source tree available via snapshot's
created nightly, CVSup as well as anon-CVS ... all documented on the web
site...

I'm sorry I didn't mean to push myself in. After all you've just met me so you don'y know if you can trust me to not damage the source tree. It's ok, I understand. I would probably be reserved as you are in this circumstance. BTW, congratulations for you dedication to the development of a capable Open Source RDBMS. >There is access to the current source tree available via snapshot's >created nightly, CVSup as well as anon-CVS ... all documented on the web >site... Ok, I am downloading it now, so I can send you the patches with cvs diff -c I presume. I am trying to figure from cvs log if the problem referred above has been fixed but I could not determine that because the log of changes since 1999-01-02 doesn't seem to mention any fixes for that explicitly. I noticed that users of other platforms seem to have a similar problem. Can you please tell if any progress was done regarding the mentioned problem?

As scrappy sez, we are always interested in having solid support for a
new platform. Is the Unix emulation library available for others
building on an Amiga platform?

The problem is on your machine. I recall that sometimes it is due to
older executables in the execution path; be sure to wipe all older
versions (or at least wipe all paths to them) before trying initdb.
Good luck.

Is the Unix emulation library available for others >building on an Amiga platform? Yes, it's kind of Open Source. If I am not mistaken there is a version of ixemul for BeOS too. A lot of Unix programs have been ported to Amiga and BeOS with it, including PostgreSQL 6.1. >> >> >> PostgreSQL 6.1 work fine but either PostgreSQL 6.2 and 6.4.2 >> >> >> (have) problems on initdb. >> I noticed that users of other platforms seem to have a similar >> problem.

Well I tried that but it didn't work. But what exactlt could be causing that cache access failed error? If I am not mistaken this is not the first platform it appears on. What exactly does it mean? Maybe I messed with something in the ported files, but I need more information to try to determine what happened.

?? It does not appear normally on any supported platform.

And so do I. Perhaps someone else will have some insight into this,
otherwise you will have to inspect your build process more closely to
identify any build errors, and then if that shows nothing then you will
have to isolate the fault. We don't have your machine, and I've never
seen your problem on my machine :(
