PostgreSQL: Primary Key / Unique conflict detection issues Forum: Help. I'm having a little bit of trouble detecting a conflict on a table with a unique constraint. Thus, it is not necessary to create an index explicitly for primary key columns. On an 8 core test server, I can sustain ~90,000 ordinary insert transactions per second on an unlogged table defined as follows: create unlogged table foo ( merge serial primary key, b int4, c text ); In all cases pgbench uses 8 clients (1 per CPU core). Here, we tell PostgreSQL to move on if a conflict occurs and continue processing the other rows: Unique constraints and primary keys are not inherited in the current implementation. When you add a UNIQUE constraint to a column or a group of columns, PostgreSQL will automatically create a unique index on the column or the group of columns. PostgreSQL UNIQUE constraint example.

Execute the following command to create a test table with one field as the unique key or primary key. When creating tables, SQLAlchemy will issue the SERIAL datatype for integer-based primary key columns, which generates a sequence and server side default corresponding to the column. PostgreSQL automatically creates an index for each unique constraint and primary key constraint to enforce uniqueness. 1. create table test(id int primary key, info text, crt_time timestamp); For versions earlier than PostgreSQL 9.5, use functions or the with syntax to implement functions similar to upsert. In this case, neither of the proposed records were added, even if only the first one had a conflict.

Let's take a look into Ecto's implementation of PostgreSQL Upsert and how different types of primary keys could change the results of this command. Indexes: "player_pkey" PRIMARY KEY, btree (id) "playerindex" UNIQUE, btree (discord_member_id, guild_id) My guess is that postgres wants the index referred to without quotation marks perhaps, but peewee is inserting them? PostgreSQL 9.5: Insert IF not Exists, Update IF Exists (Insert ON CONFLICT option) PostgreSQL 9.4: Using FILTER CLAUSE, multiple COUNT(*) in one SELECT Query for Different Groups PostgreSQL: Allow single NULL for UNIQUE Constraint Column With "equivalent" upserts, it's about ~66,000 TPS.
