[postgis-users] Installing PostGIS 2.3.8 over PostGres 9.4, Windows

[Mauro Gregorio Binetti]

Hi guys,

I have downloaded the subsequent zipfile:

https://winnie.postgis.net/download/windows/pg94/buildbot/ postgis-pg94-binaries-2.3.8devw64gcc48.zip

FOr the subsequent command:

"%PGBIN%\psql"  -d "%THEDB%" -c "CREATE EXTENSION postgis;"

shown in bat file: makepostgisdb_using_extensions.bat

I have the subsequent error:

ERROR:  incompatible library "C:/__APPL/pg94/../pg94/lib/postgresql/postgis-2.3.dll": magic block mismatch

DETTAGLI: Server has FLOAT8PASSBYVAL = true, library has false.

I have modified boolean flag value to false in subsequent files:

• pg94\include\postgresql\server\pg_config.h
  
• pg94\include\pg_config.h

but I continue to have same error.

Can you please give me some advice.

Thank you in advance.

Mauro

Which distribution of PostgreSQL are you using?

 

It looks to me like you are using a distribution incompatible with the  EDB distribution which the 9.4 binaries I built were built for.

 

For example if you are using BigSQL, only PostgreSQL 9.5 and above binaries on Winnie will work with that.

 

The reason for this is

 

Prior to PostgreSQL 9.5, EnterpriseDb used to compile their windows versions with FLOAT8PASSBYVAL =  false

So to accommodate that, I built < 9.5 with FLOAT8PASSBYVAL = false

 

However BigSQL windows distributions have always been built with FLOAT8PASSBYVAL = true

So the 9.4 builds I built for EDB WILL NOT WORK with 9.4 BigSQL

 

In Version PostgreSQL 9.5+, EDB changed their windows builds to build with FLOAT8PASSBYVAL =true as well

So from that point forward, the builds are compatible.

 

http://postgis.net/windows_downloads/

(that's why I put a note on that page that for BigSQL 9.5+, you can use the binaries here if you want extra stuff.  I probably maybe should have explained that better (and put a big DO NOT USE if using < 9.5 on BigSQL)

 

 

Thanks,

Regina

Hi Regina,

first of all thank you very much for responding so fast.

Your assumption is correct. I installed PostgreSQL 9.4.18 using BigSQL distribution.

Your explanation is very clear to me now.

I need to use version 9.4 of PostgreSQL so, I understand I have to start by changing this one. My reference must be 

https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

Correct?

Then I can repeat PostGIS installation using the same zip file:

https://winnie.postgis.net/download/windows/pg94/buildbot/postgis-pg94-binaries-2.3.8devw64gcc48.zip

Correct?

Regards,

Mauro

Mauro,

 

Is there a reason you want to use PostgreSQL 9.4 and not something newer?  PostgreSQL 9.4 is pretty old at this point.

If you can I would suggest using a newer version.

 

Note that BigSQL PostgreSQL 9.4 has its own PostGIS too.  I'm not sure which versions are offered for 9.4.  It does lack SFCGAL in it.

 

If you do from command shell (cd'd into bigsql folder)

 

pgc list

 

it will give a list of extension options.

 

Then it should be as simple as

 

pgc install postgis23

 

But if you want to use 9.4 and the 2.3.8dev binaries, then YES, you'd need to use this one

Yes Regina, it's a must due to the actual customer installation. 

Thank you very much for your suggestions. I solved every problem!

Mauro
