Note
This plugin is part of the community.postgresql collection (version 1.1.1).
To install it use: ansible-galaxy collection install community.postgresql
.
To use it in a playbook, specify: community.postgresql.postgresql_idx
.
The below requirements are needed on the host that executes this module.
Parameter | Choices/Defaults | Comments |
---|---|---|
ca_cert string | Specifies the name of a file containing SSL certificate authority (CA) certificate(s). If the file exists, the server's certificate will be verified to be signed by one of these authorities. aliases: ssl_rootcert | |
cascade boolean |
| Automatically drop objects that depend on the index, and in turn all objects that depend on those objects. It used only with state=absent. Mutually exclusive with concurrent=yes. |
columns list / elements=string | List of index columns that need to be covered by index. Mutually exclusive with state=absent. aliases: column | |
concurrent boolean |
| Enable or disable concurrent mode (CREATE / DROP INDEX CONCURRENTLY). Pay attention, if concurrent=no, the table will be locked (ACCESS EXCLUSIVE) during the building process. For more information about the lock levels see https://www.postgresql.org/docs/current/explicit-locking.html. If the building process was interrupted for any reason when cuncurrent=yes, the index becomes invalid. In this case it should be dropped and created again. Mutually exclusive with cascade=yes. |
cond string | Index conditions. Mutually exclusive with state=absent. | |
db string | Name of database to connect to and where the index will be created/dropped. aliases: login_db | |
idxname string / required | Name of the index to create or drop. aliases: name | |
idxtype string | Index type (like btree, gist, gin, etc.). Mutually exclusive with state=absent. aliases: type | |
login_host string | Host running the database. | |
login_password string | The password used to authenticate with. | |
login_unix_socket string | Path to a Unix domain socket for local connections. | |
login_user string | Default: "postgres" | The username used to authenticate with. |
port integer | Default: 5432 | Database port to connect to. aliases: login_port |
schema string | Name of a database schema where the index will be created. | |
session_role string | Switch to session_role after connecting. The specified session_role must be a role that the current login_user is a member of. Permissions checking for SQL commands is carried out as though the session_role were the one that had logged in originally. | |
ssl_mode string |
| Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server. See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes. Default of prefer matches libpq default. |
state string |
| Index state. present implies the index will be created if it does not exist.absent implies the index will be dropped if it exists. |
storage_params list / elements=string | Storage parameters like fillfactor, vacuum_cleanup_index_scale_factor, etc. Mutually exclusive with state=absent. | |
table string | Table to create index on it. Mutually exclusive with state=absent. | |
tablespace string | Set a tablespace for the index. Mutually exclusive with state=absent. | |
trust_input boolean added in 0.2.0 of community.postgresql |
| If no , check whether values of parameters idxname, session_role, schema, table, columns, tablespace, storage_params, cond are potentially dangerous.It makes sense to use no only when SQL injections via the parameters are possible. |
unique boolean added in 0.2.0 of community.postgresql |
| Enable unique index. Only btree currently supports unique indexes. |
