PostgreSQL Overview#

On Pipedream, you can leverage the PostgreSQL app to create workflows that automate database operations, synchronize data across platforms, and react to database events in real-time. Think handling new row entries, updating records from webhooks, or even compiling reports on a set schedule. Pipedream's serverless platform provides a powerful way to connect PostgreSQL with a variety of apps, enabling you to create tailored automation that fits your specific needs.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling Interval	`timer`	`$.interface.timer`	Pipedream will poll the API on this schedule
Schema	`schema`	`string`	Select a value from the drop down menu.
Table	`table`	`string`	Select a value from the drop down menu.
Column	`column`	`string`	Select a value from the drop down menu.
SQL Query	`query`	`string`	Your custom SQL Query using `$1`, `$2`... to represent values (eg. `INSERT INTO users(name, email) VALUES($1, $2)`
Values	`values`	`string[]`	List of values represented in your SQL Query above

Trigger Authentication#

PostgreSQL uses API keys for authentication. When you connect your PostgreSQL account, Pipedream securely stores the keys so you can easily authenticate to PostgreSQL APIs in both code and no-code steps.

Connecting to Restricted Databases

Either enable the shared static IP for this account below, or configure a VPC to deploy any workflow in your workspace to a private network with a dedicated static IP. Learn more in our docs.

SSL Setup

Configure SSL on your PostgreSQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.

About PostgreSQL#

PostgreSQL is a free and open-source relational database management system emphasizing extensibility and SQL compliance.

Action Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI.

Label	Prop	Type	Description
Exa (Formerly Metaphor)	`metaphor`	`app`	This component uses the Exa (Formerly Metaphor) app.
Url	`url`	`string`	"Crawl date" refers to the date that Metaphor discovered a link, which is more granular and can be more useful than published date. If endCrawlDate is specified, results will only include links that were crawled before endCrawlDate. Must be specified in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ)
Number Of Results	`numResults`	`integer`	Number of search results to return. Default 10. Up to 30 for basic plans. Up to thousands for custom plans.
Include Domains	`includeDomains`	`string[]`	List of domains to include in the search. If specified, results will only come from these domains. Only one of includeDomains and excludeDomains should be specified.
Exclude Domains	`excludeDomains`	`string[]`	List of domains to exclude in the search. If specified, results will only come from these domains. Only one of includeDomains and excludeDomains should be specified.
Start Crawl Date	`startCrawlDate`	`string`	"Crawl date" refers to the date that Metaphor discovered a link, which is more granular and can be more useful than published date. If startCrawlDate is specified, results will only include links that were crawled after startCrawlDate. Must be specified in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ)
End Crawl Date	`endCrawlDate`	`string`	"Crawl date" refers to the date that Metaphor discovered a link, which is more granular and can be more useful than published date. If endCrawlDate is specified, results will only include links that were crawled before endCrawlDate. Must be specified in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ)
Start Published Date	`startPublishedDate`	`string`	If specified, only links with a published date after startPublishedDate will be returned. Must be specified in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ). Note that for some links, we have no published date, and these links will be excluded from the results if startPublishedDate is specified.
End Published Date	`endPublishedDate`	`string`	If specified, only links with a published date before endPublishedDate will be returned. Must be specified in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ). Note that for some links, we have no published date, and these links will be excluded from the results if endPublishedDate is specified.
