# Run SQL query against all PostgreSQL tables in all databases via psql.sh
|
|
|
|
#
|
|
|
|
# Query can contain {db}, {schema} and {table} placeholders which will be replaced for each table
|
|
|
|
#
|
|
|
|
# FILTER environment variable will restrict to matching fully qualified tables (<db>.<schema>.<table>)
|
|
|
|
#
|
|
|
|
# Auto-skips information_schema and pg_catalog schemas for safety
|
|
|
|
#
|
|
|
|
# Tested on AWS RDS PostgreSQL 9.5.15
