postgresql 创建索引：ERROR: operator class "gin_trgm_ops" does not exist for access method "gin"
2024-08-27 11:56:06
g_trgm is an extension, so:
CREATE EXTENSION pg_trgm;
If you get the following error
ERROR: could not open extension control file ".../extension/pg_trgm.control":
No such file or directory"
then you need to install the module for your operating system
Ubuntu/Debian:
sudo apt install postgresql-contrib
Redhat/Centos
sudo yum install postgresql10-contrib
Fedora
sudo dnf install postgresql-contrib
