(Might be a bug) locale issue while upgrading data directory from PostgreSQL 8.4 to 9.5

Hello,

I am upgrading PostgreSQL 8.4 to 9.5 on Windows. There is some issue
related to locale. Details are as follows:

The steps that I am following are:

1. Install PostgreSQL 9.5 (8.4 is already installed).

2. Migrate data from 8.4's data dir to 9.5's data dir using pg_upgrade
utility.

3. After successful upgrade, uninstall PostgreSQL 8.4

Here the issue is that PostgreSQL 8.4 could be installed with any locale
(English or French etc.) and to have successful data directory upgrade,
PostgreSQL 9.5 must be installed with the same locale as that of 8.4.

Supplying the output of query 'Show lc_collate' (executed on PostgreSQL
8.4) to PostgreSQL 9.5 installation leads to failed installation. It
generates the error 'specified locale is not supported'.

Has the Windows version been upgraded between the install of 8.4 and the
upgrade to 9.5?

Here is the example:

Output (PostgreSQL 8.4) of query 'SHOW LC_COLLATE': English_United
States.1252

A. --locale "English_United States.1252"

While installing PostgreSQL 9.5, If we pass locale option as above,
installer aborts with an error 'specified locale is not supported'.

B. --locale "English, United States"

If we pass locale option as above, installation is successful and
cluster locale is set to 'English, United States'.

*Given that one has access to PostgreSQL 8.4, how would one know what
value to pass to the parameter --locale while installing PostgreSQL 9.5?*

Thanks and Regards,

Mayank Agrawal

No, windows has not been upgraded (Windows 7). Moreover, I think it is not
related to windows version, because I tried the scenarios from scratch on a
same machine and on a some windows version.

While working on this issue I notices something. Details are as follows:

On Windows7, I installed the PostgreSQL 8.4 with following *--locale* values

1.

*--locale "English_United States.1252"*

Installation fails, gives same error: 'Locale specified is not
supported.'
2.

*--locale "English, United States"*

Successful Installation, value of '*Show lc_collate*': *English, United
States*
3.

No Value (i.e. parameter *--locale* is not provided during installation)

Successful Installation, value of '*Show lc_collate*': *English_United
States.1252*

If you notice point 1. and 3., locale value can be stored as *English_United
States.1252* but can not be given as a value of parameter *--locale* during
installation. This seems to me as a bug.

In my case, *--locale* parameter was not provided during PostgreSQL 8.4
installation [scenario 3].

The answer would seem to be here(~/src/port>chklocale.c):

https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/port/chklocale.c;h=7a3e3af74d1554b706bef10886dc32ace61361ed;hb=aa3bcba08d466bc6fd2558f8f0bf0e6d6c89b58b

around line 195-300.

The behavior looks to be compiler version dependent.

That leads to another question, where did you get Postgres for 8.4 and 9.5?

In my case, /--locale/ parameter was not provided during PostgreSQL 8.4
installation [scenario 3].
