For current versions of PostgreSQL and pgAdmin, the “Guru” dialog warning has a “Fix it!” button or command. Use it. If there’s no “Fix it!” then we can use the Unix command line as follows. This is for PostgreSQL 9.1. Older versions do it differently. PostgresSQL docs are here: download adminpacks 8.4. adminpack functions 9.1. … Read more
By placing the rank() function in the subselect and not specifying a PARTITION BY in the over clause or any predicate in that subselect, your query is asking to produce a rank over the entire url_info table ordered by pub_date. This is likely why it ran so long as to rank over all of url_info, … Read more
At the moment it is unclear what you want Postgres to return. You say it should order by persons.updated_at but you do not retrieve that field from the database. I think, what you want to do is: SELECT date(updated_at), count(updated_at) as total_count FROM “persons” WHERE (“persons”.”updated_at” BETWEEN ‘2012-10-17 00:00:00.000000’ AND ‘2012-11-07 12:25:04.082224’) GROUP BY date(updated_at) … Read more
First, the dates need to be values of timestamp type (so append ::timestamp if you’re just specifying them as string literals). If you subtract two timestamps, the result is of interval type, which describes a duration of time (in hours, minutes, seconds etc.) You can use extract(epoch from interval_value) to convert the interval into an … Read more
You’ve basically got two choices: Option 1: A sparse table Have one column for each data type, but only use the column that matches that data type you want to store. Of course this leads to most columns being null – a waste of space, but the purists like it because of the strong typing. … Read more
Keep reading, the best options come last. But let’s clarify a couple of things first. Only silence the password request If your issue is only the password prompt, you can silence it. I quote the manual here: -w –no-password Never issue a password prompt. If the server requires password authentication and a password is not … Read more
Found the answer. It is in this line in the ALTER DEFAULT PRIVILEGES documentation. You can change default privileges only for objects that will be created by yourself or by roles that you are a member of. I was using alter default privileges from a different user than the one creating the tables. Make sure … Read more
This is a documented problem with the Postgres Docker image on Windows [1][2][3][4]. Currently, there doesn’t appear to be a way to correctly mount Windows directories as volumes. You could instead use a persistent Docker volume, for example: db: image: postgres environment: – POSTGRES_USER=attendize – POSTGRES_PASSWORD=attendize – POSTGRES_DB=attendize ports: – “5433:5432” volumes: – pgdata:/var/lib/postgresql/data networks: … Read more
Currently some locale [docs] support can only be set at initdb time, but I think the one relevant to _pattern_ops can be modified via SET at runtime, LC_COLLATE. To see the set values you can use the SHOW command. For example: SHOW LC_COLLATE _pattern_ops indexes are useful in columns that use pattern matching constructs, like … Read more
