Hi,
I maintain a Django webapp that uses postgresql and can create inefficient
queries if I'm not careful. I'm looking for ways to mimic a congested db
server in development to expose these queries.
The configuration of postgresql is complicated - is there a simple method
by which I could, for ex

Hello all,
I have a question regarding the definition of the type of a character
field in a table and more specifically about its collation and UTF-8
characters and strings.
Let's say that the definition is for example as follows:
name character varying(8) COLLATE pg_catalog."C" NOT NULL

Hello Tom,
Thank you for your response.
I suppose that affects the outcome of ORDER BY clauses on the field,
along with the content of the indexes. Is this right?
Assuming that the requirement exists, to store UTF-8 characters on a
field that can be from multiple languages, and the data

Yeah.

Hi Tom,
1. Regarding the different languages in the same column, that is normal
if the column is a UTF-8 one, i.e. should be able to hold for example
English, Greek and Chinese characters. In this case what is the best
approach to define the collation and lctype of the column? Either
Why are you specifying the collation to be "C" when the default db encoding
is UTF8, and UTF-8 has Greek, Chinese and English encodings?

Because if I don't specify the collation/lctype it seems to get the default
from the OS, which in my case is : English_Netherlands.1252 (database
encoding UTF8). That might not be best for truly unicode content columns,
so I investigated the "C" option, which also seems not to work; might be
worse
