Navicat does not have a unified default query timeout value, depending on the type of the connected database and its own timeout setting. 1.MySQL usually uses wait_timeout (default 28800 seconds). 2.PostgreSQL has no client timeout by default and needs to be configured manually. 3. SQLServer uses session timeout settings. 4.Navicat's timeout setting can be adjusted by finding the "Querytimeout" field in the connection properties or advanced options. 5. If not specified, it depends on the system or database driver behavior. If you encounter timeout problems, you should check the Navicat settings and database server configuration at the same time, and optimize query efficiency or contact hosting service support.

To print the database Schema structure from Navicat, you can achieve it in three ways: use "Export ER diagram" to generate a visual structure diagram; 1. Open the database connection and enter the corresponding database; 2. Click "Tools" > "ER Chart" > "New ER Chart"; 3. Select the table and add it, and the system will automatically generate the ER chart; 4. Click the "Export" button to save it as a picture or PDF format for printing. If you need to print the text version table structure: 1. Right-click the table name and select "Design Table"; 2. Switch to the "SQL" tab to get the table creation statement and copy and save it; or right-click "Dump SQL File" after batch selection, uncheck the data and only retain the structure and export it. Advanced users can use the report function to generate structural documents: 1. Click "

To monitor PostgreSQL replication status, you need to master the use of core metrics and tools. First, you can perform SELECT*FROMpg_stat_replication in the main library; view the connection status of the backup library, and the key fields include state (should be streaming), client_addr and sync_state; second, calculate the replication delay by comparing the difference between the main library pg_current_wal_lsn() and the backup library pg_last_wal_replay_lsn(), or directly query sent_delay and replay_delay with pg_stat_replication; finally, you can make

The key steps to synchronize the database structure using Navicat include: 1. Ensure that the source and target database connections are normal, the type is consistent and sufficient permissions are available; 2. Start structure synchronization through the "Tools" menu and select the database for comparison; 3. View the differences and corresponding SQL scripts, check the synchronization items and carefully check the impact of modification; 4. It is recommended to backup before synchronization and verify the consistency and save the configuration after completion. Follow these steps to complete structural synchronization efficiently and safely.
