hi,
when i create an unique-constraint on a varchar field, how exactly
does postgresql compare the texts? i'm asking because in UNICODE there
are a lot of complexities about this..
or in other words, when are two varchars equal in postgres? when their
bytes are? or some algorithm is applied?

The error you are seeing is triggered because this relation file
exceeds MAX_TAR_MEMBER_FILELEN or 8GB for a single tar member, which
is as well the norm for tar.
I thought PostgreSQL would break the file if it grows beyond 1GB (1GB is
segment size which one can modify while compiling). Am I

Hi, I've installed SkyTools3 on Ubuntu 12.04 Server, and got stuck when
trying to execute pgqadm.py (Step 5:
http://manojadinesh.blogspot.com.ar/2012/11/skytools-londiste-replication.html).
Does anyone know if pgqadm.py was replaced in SkyTools3?. Any up-to-date
tutorial?.

Hi all,
I'm studying pg_statistic table and I find that column staop is related to
pg_operator, and different data types relate to different staop, but I
don't know where pgsql stores the mapping between pg_type and pg_operator,
does anyone have any idea about it? thanks!

Just to add to this, whenever strcoll() (a locale aware comparator)
says two strings are equal, postgres re-compares them using strcmp().
That seems odd and inefficient. Why would it be necessary? I would think

In my project, there is a requirement to implement proximity search
feature. We are running a mobile app, for which proximity search is

The ones ANALYZE uses are the members of the default btree opclass for
the datatype. If there isn't one, it doesn't build a histogram.

Hi,
I am asking because ...
I have a table with
relpages | 19164
reltuples | 194775
pg_relation_size / 8192 yields the same number as relpages. So, there is
no need to scale reltuples. Relcardinality is therefore 194775.
Statistics target is the default, 100. So, I assume each of the 100
